I love the concept of manga where the protagonist travels back in time (not to another world though) through their own lives. Where they can try to correct mistakes of the future. I've read Tales of Gods and Demons and Tsuyokute New Saga. Know any others like it?

You can try Boku Dake ga Inai Machi aka. Erased. There's also an anime if you're interested.

Ore ga Doutei o Sutetara Shinu Ken ni Tsuite
Spirit Circle sort of, but not really. Still great though
Again!!

Haruka na Machi e -- But this a psychological slice-of-life story, not fantasy/sci-fi or thriller, so I'm not sure if it's what you're looking for.

Heptagon
Flow

I haven't read the two mentioned in your post so I don't know if they are like them.
