Seconding the XMPP reccomendation- I run Prosody, which has been rock solid and stays up even when other services I run go down. File sharing, E2EE, reactions, voice and video calls- everything you’d expect from a modern messenger. Cheogram or Conversations are great Android clients, and Monal is the iOS client I’d recommend.
