This is a small vanilla SMP on Java 1.21.11 that just started on Saturday so it is still pretty early.
Right now it has 23 members and you will usually see around 5 people online and sometimes up to 10.
If you want to join you can message the owner with your Minecraft username and get set up.
Voidcell is a Minecraft server that just released and it is all about OpPrison.
It looks like a fresh place to start grinding and seeing how far you can progress. If you like that prison style gameplay then this one is worth checking out.
I found this server called United Crafters SMP and it is starting Season 7 soon. It is a survival multiplayer world for people who like to build explore and just chill.
The server is for both Java and Bedrock players and it is on version 1.21.10. It is whitelist only so you have to apply before you can join. This keeps the server safe and friendly.
The community is 14 and older so the players are more mature but still relaxed. People like to do events team projects and other community things together.
They also have a Bluemap so you can look at the world in your browser and see all the builds and terrain. It is pretty cool for planning bases and roads.
If you want a chill SMP with a focus on community and survival this server looks really good.

Both Java and Bedrock players can join and it runs on version 1.21.10. The age requirement is 14 plus so the player base is more mature but still pretty chill.
There is also Bluemap so you can explore the world from your browser and see all the builds and projects from above.
If you like building redstone exploring or just hanging out with people in survival this server feels like a good place to play long term.
Stormy Lagoon is a survival multiplayer server that works on both Java and Bedrock. It feels like a chill place where people just want to play together and hang out.
The server runs like a normal SMP so you join and start surviving with other players. Since it is crossplay you can log in from a computer or from a phone or console that uses Bedrock.
There is also a discord community so players can talk and stay connected while they play. If you want a simple SMP that is easy to join this server is pretty cool.
