I found a server called MinecraftOffline and it runs on 1.21.11. The whole vibe is lifesteal and anarchy so people fight a lot and taking hearts is part of the danger.
It has a zero reset policy so the world is meant to keep going. The server is hosted in Finland which should feel good for players in Europe.
It also says it uses custom plugins. The machine behind it is an Intel Core i7-8700 with 64GB DDR4 RAM and enterprise HDD storage plus a 1 Gbit network.

GG.MINEWIND.NET New Server IPGun PvP SMP With Faction Politics
I found a server called StatesMC and it is a SMP that is all about PvP and factions.
The big thing here is a gun system that works without mods. People can build up and then go fight other factions and get into politics too.
It is made so you do not have to grind a ton. Factions can spend more time building shooting people and doing the fun parts.
It is for Java 1.21.11.GG.MINEWIND.NET New Server IPDeadMan’s Land Classic Factions Survival PvP

It has custom events and the pvp is meant to be balanced so fights feel fair.
