I found a small Minecraft Java server that is running on 1.20.1 with Fabric. It is a chill place with around 6 to 7 regular players and they want a couple more friendly people.
They use a custom mod list that adds new monsters plus weapons and armor and furniture. It also has RPG stuff and dungeons so there is always something new to find like a biome or a risky dungeon or gear to chase.
People mostly build bases and work on a town together then go on adventures and fight strong mobs and bosses. It is not a sweaty server and it is not focused on PvP. Everyone plays at their own pace.
They also use proximity chat and voice chat a lot. The world is getting reset soon so new players can start fresh with everyone.
