Good optional mods

So I’m a vet ck3 player and I had recently seen Tarkusarkusar YouTube video on this mod so I decided to look into as a Bethesda player so I know that the mod is going to be updated but since it’s not right now I wanted to know what would be good mods to download alongside this when it does get updated and any major compatibility issues with popular mods since I couldn’t really find any information?
