Yeah, this used to be a problem, but it has been working fine since Fedora 39. I can share a single window or the whole screen with the video conferencing tools I'm using, mainly Signal, sometimes Google Meet, Teams (both in Firefox running natively on Wayland) and Zoom.

Flatpak has made it so easy to install most common apps, just press the Super key, search for the app, click on it in the list and "Install". Usually takes less than 10-30 seconds from start 'till the app is installed and running. Very grandma-proof, actually!

EDIT: But I will say that the road to where GNOME / Fedora is today has been a bumpy ride, like a car that is under maintenance while driving :) It's the FOSS / Linux way. In the end, the result is actually quite amazing and user friendly.
