Rosedalean SMP is a Java server on 1.21.10 that feels like enhanced vanilla. It has a mix of casual and hardcore players so it does not matter how you like to play.
The server uses add ons so you do not need to download mods. There is an application system to help keep trolls out and the community is meant to be welcoming for new players.
You can join factions or make your own and there are community run events too. It also has Simple Voice Chat for talking in game plus Terralith biomes for better exploring.
There is a ticket system if you need help and a BlueMap so you can see what the explored world looks like. They also do weekly game nights and they say they listen to player suggestions.
