I found a modded SMP called Jujutsu Origins Reborn and the big hook is the Jujutsu Craft mod by Orca. It is a standard survival world but it has a deep power system and a lot to learn.
You use cursed energy and a cursed technique to get stronger. Progression is based on grades and you go from Grade 4 up to Special Grade. If you push far enough you can reach things like domain expansion.
This server is not super casual if you want to climb fast since it takes skill prep and grinding. It can still be chill if you just want to roleplay a character and hang out. They also talk about adding lore later.
To start you join their Discord then you make a spin ticket so your technique can be rolled. If you do not like it there are events and trading so you can try to get something else. You also pick sorcerer or curse and that mainly matters for team events. Then you download the modpack add the IP and jump in with rtp if you want.
