I'll give you 4 recomendations:

Stardeus: Rimworld, in space!! It's super fun and has a lot of QoL changes, I even worked in the development. It has a free full demo, you will not regret: https://steamoss.com/steamstore/app/1380910/Stardeus/

Captain of Industry: This is like Factorio, but the terrain is diggable and its very realistic and well optimized:

Final Upgrade: This is about ship building and resource managing-factory like in space, where you can build and automate ships to extract resources and fight: https://steamoss.com/steamstore/app/919260/Final_Upgrade/

Song of Syx: city builder like dwarf fortress, very deep and has a lot of systems and wars: https://steamoss.com/steamstore/app/1162750/Songs_of_Syx/


Bonus:
To the core: small incremental game about drilling a planet core, very fun https://steamoss.com/steamstore/app/1988550/To_The_Core/
