XMPP just works and has matured substantially in the last 5years or so. You may or may not like it, but that's all I've been using/needing for a decade, and because of that, I ended up onboarding a bunch of tech-illiterate friends and family members along the way. It just works for them, too.

I "need"/want more, Cross Signing, completely autonomous servers, not contacting 3rd party servers as a client, easy access to e2ee msgs including fresh sessions, non-centralized rooms, e2ee video conferencing, to name to most important aspects.
