Stormy Lagoon SMP is a survival world where Java and Bedrock players can play together. It feels like a chill place to just hop on and hang out.
You can join from both Java and Bedrock so it is easy to play with friends no matter what they use. It is a normal SMP style server where you survive and build and explore.
The community talks together on Discord and the owner is easy to reach. If you want a simple crossplay SMP without a lot of extra stuff this server is pretty good.
