I found a normal SMP that is launching on Feb 20. It is meant to feel simple and close to vanilla.
There is no economy system and it is not modded. It uses only a few plugins but they are not supposed to change gameplay much.
The server supports crossplay and it is up 24 7. They also say there will be no resets so your stuff can stick around long term.

GG.MINEWIND.NET New Server IPVoidMC Vanilla Plus Dungeons No Resets
VoidMC is a recently launched Vanilla plus survival server on Java 1.21.11. It stays playable on a normal vanilla client since it only uses datapacks.
The world is permanent with no resets so your builds and progress stick around. You can roam through custom world generation and new biomes then stumble into discoverable structures and dungeon style content.
There are custom mobs plus custom items and enchantments to find while you explore. If you like survival that still feels vanilla but has more to see this one is worth checking out.GG.MINEWIND.NET New Server IP
