Stormy Lagoon is a survival multiplayer server where Java and Bedrock players can play together.
The server feels pretty chill. It is focused on survival and just hanging out with other players. It does not say anything about crazy plugins or custom stuff. It is more like a simple world where people can join and play.
There is also a discord community so players can talk and organize things together.
If you just want a basic SMP with crossplay support this server looks like that kind of place.
