ahh yeah, i heard nvidia can be a pain in the ass with sway/wayland. did you try sway when you still needed the --my-next-gpu-wont-be-nvidia flag lol?

but i remember reading about some new driver that made things much better... no idea though i've always been on intel-only laptops

mixes dpi

never had any issues with that. although i don't think i even have anything going through xwayland at this point

apps to interact with ppl

zoom? or something electron-based?

xcape

i don't know the tool, but the readme sounds like evdoublebind might work, it's rock solid for me, replacing caps lock with escape on tap/alt om hold

screensharing

i feel you. when i started out with sway i had this horrible hack running a vnc server and a x11 vnc client on the same machine because pre-pipewire browsers could only share x11 windows haha

but nowadays that works really well. only zoom is still a little annoying ux wise. sometimes their screenshare popup just disappears leaving me with no way to stop a share gracefully.
