I found a chill modded Minecraft server called The Ferox Concordium and it is run by a small group of friends. It feels welcoming and they are trying to grow the community.
The server is always online and people are actively playing. It is running the Divine Journey 2 modpack on Forge for Minecraft 1.12.2.
Staff and owners are around a lot and they help when you have questions or need help in game. Joining their Discord is required so they can verify players and keep things safe.
It is 16 plus only and they want everyone to be respectful.

GG.MINEWIND.NET New Server IPEarth War Nations Modded Chaos

This is a Minecraft server that plays on a full Earth map. When I joined it felt like everyone wanted to build huge bases and then immediately point missiles at each other.
The server is modded and it uses Create so people can build giant factories and crazy machines. Some players are really into making everything super efficient and they even talk about using spreadsheets for their setups. It is all about industrial overengineering and making your industry bigger than your neighbors.
There are also warfare mods like Superb Warfare and Simple Planes. That means you can fly jets and drive tanks and blow stuff up. Fights can turn into real wars between nations and people like to argue about geopolitics then back it up with actual weapons in game.
The whole idea is to build nations and create your own power. You can work on your economy and basically print money and ignore things like the Geneva suggestions and go full chaos if you want. It feels like an Earth server that is meant to last and not just be a big argument in chat.
If you want a modded Earth world with nations warfare and big factories this server is built for that.
