I found a server called Trotuserver and it feels like a vanilla world with geopolitics. The big thing is there are no map resets so your builds can stay for the long run.
There are no land claim stuff and no teleporting. It is more about traveling and living with what you build. People make towns and nations and you can join old ones or new ones or start your own.
The server has been around for about 7 years so the world has history. It is a good place for big projects and worldbuilding and also roleplay if you like that.
It also allows Litematica EasyPlace with the setting that helps blocks place in the right direction. There are some datapacks for convenience and a plugin called Brewery for making drinks. There is also a custom resource pack and players can contribute to it.

GG.MINEWIND.NET New Server IPOne Year Old Anarchy World

MinecraftOffline is an anarchy server that has been running for a year so it feels like a real world with history.
It is on version 1.21.11 and the map is permanent so stuff stays.
The server uses a custom plugin suite and it is hosted in Finland so it should feel good for players in Europe.
It also has solid hardware and a 1 Gbit network so it is built to handle people playing for a long time.
