I found a server called Lumenor SMP and it tries to do stuff different from a lot of other servers. The community is said to be polite and the staff helps fast. Even when staff is not around people in chat are supposed to help you.
It runs on the latest version 1.21.11 and it also lets in 1.21.4+ players with ViaVersion. It supports Java Bedrock and even cracked so you can join from more places.
The server has a role system so peaceful players can do their thing and the chaos players can fight and grief. There is also a trading style shop where players put items up and trade like villager trades.
The world is described as custom vanilla with custom biomes and big structures like ancient temples. There is an arena for PvP where you can fight without losing your items because keep inventory is only on in the arena. It also mentions trims that give small buffs and a custom nether that should be opening around now plus a strong anticheat to catch hackers.
