I found Konohaven SMP and Season 5 just started and it is trying something new. It is a semi vanilla Java survival server on hard difficulty.
This season the players get to make a lot of the big choices. Stuff like spawn plans shopping areas and roads are meant to be decided by players. People can form committees or run solo and argue it out with builds.
There is no set world border. Chunks will be generated out to 1500 at the start to help with early lag and after that you can explore as far as you want. The seed will be public and the world generation is being tweaked to add new vanilla style features.
It has single player sleep and a live map. Simple Voice Chat is optional and you do not need mods to join. Blaze and Caves Advancements are on with less chat spam. There is also an optional origins datapack and the origin choices will be explained before you pick.
The server is located in the Eastern US in Virginia.
