As an FYI, for folks reading this, I spend at least half of every day in video conferences and this is largely a non-issue these days. The vast majority of platforms have web-based clients that work great, and many have native clients that are quite good as well. The biggest issue is probably screensharing on Wayland, which can be fiddly to get working and is subject to client issues, so stick with Xorg if you can.
In terms of hardware, I just end up buying gear designed to work with Linux rather than trying to make Linux work on a random piece of equipment. That means typically Dell or Lenovo, though newcomers like Framework are also prioritizing Linux support.
If you're using just random gear, older is better, as Linux support comes eventually but it often lags.
Edit:
By the way, I have to say, I've appreciated a lot of the comments in this thread. While I don't myself have the deep affection for the mac trackpad, and so can't really comment on that experience, everything else in this comment thread absolutely rings true to me.
And I say that as a person using Linux as a daily driver!
