XMPP runs very well on the pinephone (I'm using dino from guix but there are a dozen clients, finch works well if you want something in tmux.)
Most modern clients support a handful of encryption standards (OMEMO is similar to signal and has PFS.) There are plenty of XMPP clients even on iOS that support real time push notifications from what I hear. If your friends don't want to create accounts you can run a server yourself fairly easily (although not quite as easily as miniircd unfortunately.)
Most people here in the US just use MMS though and since no one else wants to put effort or thought into this that's what all my friends end up using.
