Last I checked, the competitors, whether free or not, all had meaningful downsides (quality, latency, self-hosted, inextricably bundled to another system, etc) with the only upside being “it’s not Zoom.”
Honest question. I’m sure the land has changed a lot in the last 6-12 months.
The one I was kinda surprised wasn't any good, even for audio-only, was Discord. Not that it fits your criteria anyway.

My mother, for example, still prefers correspondence via snail mail. She has learned to tolerate FaceTime, but Zoom is always a bit of a hassle and requires a separate phone-call to her landline to help her walk through the steps to get connected. I don't think she's unusual. It's a big world, with lots of kinds of people in it.
Yes. Google Meet is just as easy to use, and Jitsi is even easier with zero signup required.
