I found this server called Everbloom SMP Network and it has two different ways to play so it feels like you can pick what you like.
The Everbloom Survival side is more intense. The season starts on 13th December and it has full farming and redstone support. You can also use the nether roof. PvP is on and raiding is allowed so you always have to watch your base. There is a 75k world border and only diamond gear is used and there are no maces so it stays pretty balanced.
The Everbloom Casual SMP is for people who just want to chill and build or explore. There is no PvP no griefing and no raiding at all. It has custom terrains and structures but still keeps a vanilla feel. You can build farm and create with other friendly players.
The whole place feels relaxed and wholesome and the community is focused on creativity and cooperation. It is good if you want either a peaceful survival world or a more risky raiding style world in the same network.

Enable Fishing Rod Stasis Glitches

I found a Purpur server running on 1.21.11 and it is all about letting players use stasis glitches.
The main thing people ask about is getting the fishing rod stasis glitch working by changing the right lines in the yml files. This place feels like it is for players who like testing weird Minecraft mechanics and messing with server settings to make them possible.
GG.MINEWIND.NET New Server IPNo Rules Vanilla Chaos Survival

I found 1fighter2defenders and it is a survival server that tries to stay as vanilla as possible
There are no gameplay rules and there are no admins running around fixing stuff. There are no land claims and no protection so anything can happen. Griefing building and cheating are all allowed and it is basically anything goes
They also say there are no server sided dupes and the world does not reset. The server started in April 2021 so it has been around for a long time and lots of players have visited
It runs on 1.21 and you can join from 1.17 to 1.21.11
GG.MINEWIND.NET New Server IPAlmostAnarchy Vanilla Semi Anarchy Survival

AlmostAnarchy is a vanilla Minecraft server with a semi anarchy feel where you get a lot of freedom to play how you want.
It runs with almost no plugins so it feels close to how the game was meant to be. Hacks and cheats are not allowed.
The player count is usually small around 3 to 5 and peak can reach 10. Even with that the community is really active and people have made some impressive projects you can check out when you join.
It is a survival world where you can run into people at random. You can team up or test your skills or go all in on huge building projects.
GG.MINEWIND.NET New Server IPAshenreach Survival With Relics And Real Wars

Ashenreach is a long term public survival server where the world feels grounded and lived in. People still build explore travel and team up but the setup pushes real choices and real conflict instead of everyone being untouchable.
The big hook is custom relics that are hidden around the map. There is a tracking system so relics can be hunted even if they are in a chest in lava or being used by another player. The world is still early so new players can jump in and not feel locked out.
Enchantments are rare so fights stay more fair and gear feels earned. Healing is slower too since it uses UHC regeneration and you need a campfire to heal. The map is handcrafted with custom terrain structures and regions.
SimpleVoiceChat is on so you can talk in game. There is a lands claim plugin for ranks and permissions inside your land but it does not fully stop theft so you still need to plan and defend. The server is meant to last and it has no resets and no ranks or shop.
GG.MINEWIND.NET New Server IPKronos Geopolitical SMP Nation Rush

I found a new SMP that is about geopolitics and nations. It is starting soon and people are trying to join early so they can claim land they want.
There are already over 40 members and it sounds like it could get way bigger fast. Nation creation applications open within a week so the early joiners get the best shot at planning territories.
The server uses mods like Brewery and Immersive Aircraft to make things more interesting. The map is 20000 by 20000 and they said it will expand as more players show up.
