I found a Vanilla Minecraft server that is for 18+ players. It is meant to feel like normal Minecraft and you can just hop on and play.
It has land claims so your builds stay safe. It runs on Fabric and it is made so redstone and farms work like they should.
The server is hosted on a dedicated machine with a Ryzen 9800X3D so gameplay is super smooth. There is no pay to win stuff so it stays fair for everyone.
