I found this server called Althaia MC and it feels really chill. It is a vanilla style survival world but with some RPG elements to make it more interesting and not boring.
The server is made for all kinds of players. You can be a beginner or someone who already knows everything about Minecraft. You can just relax and build or you can enjoy some PvP if that is your thing.
The world is open 24 7 and the owners say they take care of it every day. They keep working on new features so the server does not feel stale.
It also works on Bedrock in an experimental way so you can even join from your phone if you want to play on the go.
Overall it feels like a place where you can log in after school or after a long day and just hang out with nice people and start your own adventure.
