I found StarBorne and it is a sci fi story survival server that works on crossplay. The idea is that Earth got ruined by wars and chaos so the last survivors got sent to a new planet called Alpha Centauri.
You are supposed to regrow civilization by making towns and building a base. You can explore unique structures and try to make this new world feel like home.
The terrain is made to be inspiring but still good for survival. There is also custom music to help the world feel more immersive. This is Chapter 1 called Alpha Centauri and it is season 1.
There is a big mall called Arcadia and you can use the shop command to visit it. Since the server is new you get the highest rank called Pioneer forever for free when you join.
It is meant to be simple with some quality of life features and a focus on survival.
