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.

The ShadowSMP is a small chill Java SMP with a few cool plugins. It looks like a place where you can just play survival and relax.
They have around 20 players right now and they are trying to build a fun active server where everyone can have a blast together.GG.MINEWIND.NET New Server IP
