I also used my own xmpp server for my family. But I switched back to signal because xmpp client doesn't crypt data on client devices.
SimpleX is easy to use like signal and is decentralized (with tor relay). I tried it since weeks but I don't have my family for now. It's hard to make people switching over and over.
The big cons about Signal is it is centralized so it has a single point of failure and can be easily censor.
