I found this server called Team Extreme and it is all about factions and pvp and not an smp at all.
You join and pick a side and focus on fighting and building up your base. The whole thing is about progression and grinding and getting stronger so you can win more fights.
There are multiple open worlds so you can mine and explore and keep moving around. It feels different from the usual smp servers because it is made to be a clean factions server with its own ideas and not just some copy paste server.
The server is on version 1.20.1 so it uses newer stuff from the game.
