As one of the resident luddites around here. I've got a Cateye Astrale (wired with cadence) on the right side of my handlebars. It even moved there from my previous bike over 10 years ago. Its super reliable and only needs a new battery ever 2-3 years or so.
The left side has seen several Garrmin and Wahoo models that all got replaced for a variety of reasons but mostly because they weren't operationally reliable.

If all you really want is the basic data for your ride and don't give a rat's posterior about where you are or going and all the other highfalutin training data points that these newfangled internet connected models offer, I seriously suggest:
