CaliCraft is a player run democracy server based out of California and it has multiple gamemodes you can jump into from a lobby.
The big twist is the Emperor elections every two weeks. Players vote and the winner gets real power over the server. They can add or remove plugins across gamemodes and make laws and even imprison people including staff. If you get marked as a fugitive you can end up spawning in prison when you die or get dragged in if caught. The Emperor still has to follow a Constitution and temporary laws can happen during their reign. Some laws can turn permanent through a Discord poll.
There is Modded Survival with custom enchantments and skills and jobs and an auction house plus an economy and custom dungeons. It also has vote crates with strong gear and it is a claim world with a kingdom run by the Emperor.
There is also Vanilla Survival with quality of life stuff like quests and chest sorting and daily rewards. Skyblock is here too with classic island gameplay and some extra addons.
Cobblemon is a separate Fabric server and you need the Cobblemon modpack to play it. You can catch and train and battle Pokemon in Minecraft and you can swap over using the cobblemon NPC at spawn or the server command.
The server also uses a custom resource pack with unique mobs and animals plus elites and dungeon bosses with special drops so it does not feel like normal vanilla exploration.
