Signal doesn’t offer anything except sms 2fa and requires a phone number. It’s a terrible choice considering LEO can do what they did here and just get legal access to MITM your sms messages, spoof the 2fa, and take over your account, impersonating you. The other ones aren’t encrypted. So none of these they broke into are great choices for truly secure messaging.
