I've been remote since around 2017, calls almost daily - maybe twice my lacking video has come up

I deliberately don't have a webcam, my team never uses theirs, so it works out pretty well

I wouldn't do well in an environment where it "mattered", if being on camera became a recurring topic I would certainly leave.

There are more important things to worry about, and if a place makes this significant, their priorities are broken

I would entertain it as a team dynamic, what you describe (and my 'firm' stance attempts to mitigate) is electronic supervision

I'm a professional, if you can't tell by my work that I'm here/active, I'll do it somewhere else.
