Take a look at some Bryton and Lezyne GPS computers. Even if you don't need the GPS or use Strava, these are very versatile computers. They're compatible with most sensors (I started with heart rate, then added speed and cadence). Combined with an app to check my heart rate variability it helps motivate me to train a little harder within my limitations, and reminds me when to take it easy or take a day off.

I considered a Cateye Padrone a year or so ago, but realized for the same $50 or a little more I could get an entry level GPS computer and save my phone battery.

The Bryton Rider One, 10 and 15 appear to have larger than usual displays.

Lezyne computers vary quite a bit in size and reported ease of use. I think the Macro Easy is considered their easiest entry level computer that's also easy to read.

I got a XOSS G+ in January and am satisfied with it, although being a Chinese company the pandemic hit them had and they were incommunicado for a couple of months. I never had any problems with mine, but some international customers said complaints went unanswered.

So while it's a good value, XOSS wouldn't be my first suggestion now. And it's quite small -- I need the +1.5 diopter on all my riding safety glasses to see anything closer than arm's length. Bryton appears to be the best overall value in entry level bike computers.
