I found FreakCraft and it is made for people who want real vanilla survival. It runs on the normal minecraft server jar with no plugins and no datapacks.
The server keeps it simple so there is not a fancy confusing spawn. You just join and play how you want. Build what you want and do your own thing.
There is no tp and no sethome so you have to travel the normal way. Players are expected to handle their own social problems too. Technical Minecraft players are welcome and it stays on the latest stable vanilla jar on a self hosted machine.
