XMPP does, but how advanced depends on the client used. Only the Movim and Dino clients support group voice/video calls at the moment, and Movim is the only client that supports Screensharing (requires a Chromium based browser to screenshare w/audio).
I’m not too sure, I didn’t look terribly deeply on that front since that’s not something my group uses often, and its difficult to test on my own. That said, I believe Matrix does have some level of voice chat support, though AFAIK its more similar to Skype’s calls than Discord’s drop-in/drop-out voice channels. No idea about XMPP though.
I belive just Matrix and XMPP.
Do they have voice chat integration? It’s not a big deal for me, but for a lot apparently it is.

Yes XMPP supports voice. Had for well over a decade, maybe two.
