I found a server called MinecraftOffline and it is all about lifesteal and anarchy survival.
It runs on version 1.21.11 so it feels up to date. The play style is pretty wild since you can fight a lot and the lifesteal part makes every fight feel risky.
It also has a zero reset policy so worlds are meant to stay. It is hosted in Finland which should be nice for players in Europe.
They also say it uses custom plugins and the server is running on strong hardware so it should handle busy moments better.
