Tom Riddle and the Black family sound more intriguing than the others, however, if it has great prose I'll take them all.

 

You are correct on the Star Wars one. as For Naruto, there's only one that I think really fits the bill but it's unfinished and it's not really beautiful prose but it is extremely well written and descriptive. I'm not entirely sure it fits the bill honestly. The only other one I can think of that even comes close is Iga Naruto which is currently updating. Sorry if they don't really fit the bill but I'm not really one to go looking on my own for stories so most of the ones I've read are recced here.

 

I guess I may be alone in this(?), but I would also recommend Shezza's stories. There's the Denarian series and one where Harry controls Azkaban, and I recall enjoying a good balance of exposition and imagery in both. I always felt a distinct kind of immersion that managed to be engaging without being overly pretentious, though this is in the standard order of praise for those stories. I didn't see them mentioned, sorry if someone already recommended them.
