I disagree about the tinkering, I've found it very straightforward to get a decent desktop experience. The only drawback is that it's perceptibly slower than Linux.

Your mileage may vary, depending on what you compare with. It's definitely not hard, but setting up OpenBSD does require more work compared to setting up something like Ubuntu or Linux Mint.

Can you do screen sharing ?

I don't know if Teamviewer or Anydesk support *BSD, but you can always use xpra - though they say "All BSD variants should work, but are not regularly tested." so you might find a couple hiccups maybe.

I've found xpra --shadow to be almost on par with Anydesk on Linux - even passing through an ssh proxy. But obviously that might depend on GPU encoding which might not always be available on BSD.

I meant screen sharing on Teams, webex, zoom, etc
