I found a community centered survival server that is built around a Hermitcraft style SMP feel. It is made by the players and it tries to keep that vanilla experience while still adding small extras.
There is a diamond based economy with a shopping district. You will also see public builds and bigger projects that people work on together. Proximity chat is a big part of the vibe and most players actually use it.
It is Minecraft 1.21.11 on Java only. The server is whitelisted and it is 18 plus only. You can expect around 5 to 20 players online through the day and a lot of regulars plus groups that want new people to join.
