Here's a great example from dessalines' great "Why Not Signal?" essay on what makes a good messaging platform. https://dessalines.github.io/essays/why_not_signal.html#what-makes-a-good-messaging-platform
Notables include:
End-to-end encrypted
Open source
Federated
Self hosted
No required linkable identifiers (and no Signal's recent announcement on them hiding phone numbers doesn't even count.)
Good messaging alternatives include:
Matrix. XMPP, Briar, SimpleX
