Zoom supports the xdg-desktop-portal for screensharing as of semi recently.
Sway's screensharing portal (via xdg-desktop-portal-wlr) only lets you share a full monitor at a time. You cant only share a screen region or a single window, so YMMV.
Some of the big proprietary clients have their own devs using linux. Devs tend to be that type of person, so them pushing for upgrades to tools they themselves use isn't too surprising. Discord just recently released an official flatpak and cited internal dev teams as a reason.
I run it as a Wayland client since a year or so now.
The only problem I know of is that screen sharing does not allow you to select an audio stream which has already spawned multiple hacks / modded clients over the years (and might also apply when running as a X client IDK)
