I found a Minecraft server called PGMC that lets you pick how you want to play.
You can swap between survival creative and vanilla using simple server commands. It feels like a place made for people who like switching it up without leaving the same community.
It also supports Bedrock players which is nice for friends who play on different devices.

Stormy Lagoon is a simple SMP server where you can join from both Java and Bedrock.
It looks like a place to just hop on and survive with other people. You can play however you want and just chill and explore and build.
The server feels like it is more about crossplay and just hanging out instead of tons of crazy plugins. You can join from your PC or your phone so it is easy to play with friends.
If you want a basic survival world with other players and you like both Java and Bedrock this server is made for that.GG.MINEWIND.NET New Server IP
