@lemmy.mlIf I understand it right,
Please correct me if I'm wrong.
SimpleX has the best privacy, because of removing metadata.
Signal comes close, and has many more users. Probably some of your friends already use it.
If you want something similar to Telegram/Discord/Slack, then Element (Matrix) is what you're looking for.
All of the above are E2EE.
I just found this. Haven't tried it.

You can just continue using Signal. All the alternatives will disappear from the app stores too unless they spy on you.
A recent alternative with even better privacy is SimpleX: https://simplex.chat/
