I found a modded SMP that two sisters are building together and it feels like it is made for people who want a real community.
It uses a custom modpack called Runic Engine and it has four progression paths that connect to each other. There is mystic stuff with magic and rituals plus mechanic stuff with machines and automation. There is also adventure for exploring and combat and homestead for farming and economy.
The whole point is that nobody has to rush endgame. They want teamwork and shared projects and people helping each other. They also say it is long term and there are no wipes planned. Development is active and changes are based on feedback.
