I found a small Minecraft Java server that is running on 1.20.1 with Fabric. It is a chill modded world with about 4 to 5 regular players.
They use a custom mod list that adds new monsters plus weapons armor furniture and more. The main idea is to explore and build a world that feels lived in with cozy bases shared towns and paths.
It is not a sweaty place and it is not PvP focused. People play at their own pace and it is more about relaxed teamwork and good vibes.
They also use proximity voice chat so you can talk while building or when you run into someone while exploring.
