I found OakenvaleSMP and it is a survival server with a medieval theme. It is about building cool towns and castles and pushing progression while you explore.
Players can start towns and kingdoms and make alliances or compete. There is a player driven economy and the vibe is more like medieval RPG survival.
It has some QoL plugins plus custom biomes and extra random world structures so exploring feels more interesting. There are claims and a teams system so people cannot destroy or loot your builds.
There are daily and hourly rewards you can check in game with /rewards. The server is on version 1.21.10 and it is hosted in England. New players are welcome.

GG.MINEWIND.NET New Server IPKingdoms Semi-Vanilla Geopolitical Roleplay
I found this Minecraft server called Kingdoms and it is all about semi vanilla roleplay. It runs on version 1.21.10 and it is whitelisted so you have to apply before you can join. The whole idea is player driven politics and big geopolitical stories between different players.
On this server you can create your own kingdom using a custom mod. You can change how your name looks in the tab list and in chat so you can really act like a new character. People make alliances and enemies and build up power over time.
The server has a 24 hour ban if you die in PVP. That makes every fight feel scary and important because if you lose you are gone for a whole day. There is also voice chat so talking and roleplaying with others feels more real.
They use improved terrain and Carpet Mod with player commands to make things smoother but they still keep all the normal vanilla game mechanics. They even bring back old things like string duplication void trading and update suppression for players who like that style.
The community seems focused on serious roleplay and careful survival. If you like kingdoms politics and making your own story this server is built for that.GG.MINEWIND.NET New Server IP
