Recording distance on a GPS doesn't cost anything extra.
This is a big reason why why the device the OP wants doesn't really exist.
Maybe, the OP doesn't realize that location is the primary data for GPS (and speed is derivative).
The OP really needs to understand more about how these things work.
What he wants isn't exactly unreasonable. It just seems there's no market for it. That is, no manufacturer sees the exact thing he wants cheaply to be worth making.
The USB-C requirement is a problem because the manufacturers of cheap devices aren't going to see much (any, really) value in redesigning/requalifying what they are already making (and know works) for this minor thing.
A watch would be a good choice for him but it's too expensive and a bit harder to use than he lists as a requirement.
What he needs for the bike is a simple non-GPS cycle computer (that's exactly what he needs there) but he makes that impossible by the complication of needing to use it on the SUP.

Basically, these computers never turn off. They just go into a very low power mode and "wake up" when they detect a signal from the sensor.
It doesn't really cost more to do this because it's using the parts it already needs.
It works well because "wheel is rotating" meaning "you're riding" is reliable (it's not perfect).
A GPS doesn't need an accelerometer. So, using one is an extra cost (you won't see one on a cheap device).

EU wants to mandate USB C for everything. Fortunately, watches still be exempt.

There's a good chance anybody designing a new device would choose USB-C even without this resolution (except manufactures trying to be real cheap).
Anyway, is anybody using a proprietary charger? Laptops seem to be going towards using USB-C already. There are differences (sometimes very significant) in power output but that isn't addressed by this resolution at all.
Chargers have been standard for quite a while and plug differences are dealt with by using a cheap cable.
=========================
https://www.europarl.europa.eu/news/...ectronic-waste
Rapporteur Alex Agius Saliba (MT, S&D) said: “With half a billion chargers for portable devices shipped in Europe each year, generating 11,000 to 13,000 tonnes of e-waste, a single charger for mobile phones and other small and medium electronic devices would benefit everyone.

It's a pretty safe bet that was law that might be passed in the future won't change how things were already manufactured in the past. Thanks for pointing that out, I guess.

It’s not going to change much for things made in the future (except iPhones): things were already moving towards USB-C.
And it doesn’t address the problem that is said it addresses.
It might nudge cheaper manufacturers to use USB-C in new designs sooner but they still aren’t going to make the particular device the OP is looking for.
The resolution doesn't change anything and doesn't help the OP at all. So, it's odd you even brought it up (and complain about people discussing it).

On very tiny electronic assemblies like in watches, the issue with a USB-C connector is the internal real estate. That's really valuable volume for a designer and the tradeoff is giving up the volume to a waterproof USB-C connector instead of to a bigger battery. Far and away, the smarter choice is for more battery. FWIW, a USB=C connector is pretty big in the grand scheme of things at this scale.
I'm thinking this answers the whole question. It's either going to be to get something you aren't entirely thrilled about because your feature set does not exist in a product. So you just do without.

Someone mentioned GPS drains the phone battery. That is totally irrelevant. I never turned off GPS unless maybe on an actual airplane. Using the screen uses a lot of battery, but GPS is almost nothing compared to all other phone functions. For a small watch battery GPS may matter,. but not for a modern phone. And the overall benefit of GPS to show me on a map where I'm and where I came from outweighs any battery use. Better than any map.
I'm glad someone brought up the (hopefully) upcoming EU regulation regarding USB-C. That is a huge accomplishment to simplify life and reduce waste and those extreme prices manufacturers charge for ever-changing proprietary cables. I'm glad I'm not the only crazy person wanting a single type of cable.
I'm still at 50% of my devices on micro-USB and it will take me years to get them all to USB-C. Until then it is taking many more cables with me (I always take 2 of each, in case one is broken).

My Garmin Instinct 2 Solar is now on 40 some odd days without being charged, running GPS all that time. If I do tracking with it, battery does run down, but its got remarkably good battery life that in theory, can run forever if you solar charge it enough.

I'm the opposite. For any tracking I don't need to know how many miles while doing whatever I do. I only need to do that later at home (and may or may not post the route and pictures on facebook etc.). I don't even think the Samsung app shows me the distance so far until I "finish" the activity. But what I need while riding/hiking/boating is the map to explore and sometimes to find my way back. I really only get the phone out to take a picture, or if I need to make a decision on where to go at a fork.
Usually the way I prepare for a hike, I'll know there's a trail junction at 5 miles, so I'll keep an eye out for it when I've gone about that far.

The EU regulations really only affect Apple lightning cables. And reasonably priced ones have been available for many years.
No other manufacturer uses proprietary cables for phones (they haven't used proprietary cables for many years).
The standard for (non Apple) phones was microUSB (and has been for years). They have been moving to USB-C for a while already (without the regulation).
And USB-C cables haven't been one thing either.
The EU regulation is about 10 years too late. The things it is trying to do where mostly already happening (except for apple cables).

Someone mentioned Garmin Instinct. Some refurbished units cost $150 and they look like they do what I would want. Their manuals don't specifically say, but some pics look like it, they seem to use USB-C. Is that correct? What other wearables use USB-C and can be had for say under $200?
I saw some watches use some proprietary clamping cable. That seems to be a big step way backward since cables can and WILL fail and I really want to avoid having to bring different types of cables (I always have USB-C with me for the phone).

I'm really surprised manufacturers are not specific with the the type of charging cable. I looked through many manuals and none really say what cable they use, or just say "USB". And the pictures never show the type of plug the cables have.
the watches I saw say they last 24 days, but with GPS use only a few hours. So that makes them less suitable for ME since the GPS is main function for me for speed.

What about a cheap wired unit with replaceable batteries. Are those still made. Something that's sold in the bike section at Walmart/Target for $19.95.

Is it possible to charge the hammerhead karoo 2 during a ride ? Thats a requirement for me.

Pretty much all bike computers can be charged off a regular external battery whilst riding and the Karoo being basically an Android phone customized as a bike computer will be able to.
And not sure why the post about the Cyplus M2 was ignored - it's $46 and has Usb C so it ticks all boxes.
Also the Bryton S500 is usb C (but not cheap)

I'm not 100% sure if all computers will function while plugged into a battery bank, but it might not be healthy for the computer if the temps are winter like conditions.
I've been meaning to try slaving the wahoo elemnt with a battery bank while it's in use, but I just haven't had the need to do it yet. Also, it's been too cold.
