I found Omni World and it feels like a server made by someone who has tried a bunch of different Minecraft servers and wanted to keep the classic vanilla feel but still add some twists.
The community has been around for years and they seem really close. The server is called Omni 4 because they have made three servers before this and now this is the official one.
It sounds like players get a real voice here and your ideas can shape what the server becomes over time. The owner also says they want to be mostly hands off so the server can mature and feel like the older servers people remember.
