I found a cozy survival SMP that lets people play together on Java and Bedrock. It supports Java 1.9 to 1.21.11 and it is crossplay.
The world is a little progressed but it still feels early. The most active time is usually GMT-6 afternoons.
They want a few chill long term players who like to build and chat and help grow a small community. They are not planning resets so it is more about relaxed survival vibes.
You have to join their Discord to read the rules before you play.
