2nd time reincarnated into same world / Regressor type manga recommendations please!

[vexxar]

As a fan of the isekai genre, the only thing better than being reincarnated to a fantasy world is being reincarnated a second time knowing everything about the future. Basically I'm looking for manga/manhwa in which the protagonist has substantial knowledge about the world already and future events and uses these to not make the same mistakes in his past life.
Some popular Examples are:
1.The Descent of the Demonic master
2. A returner's magic should be special
3. Ranker who lives a second time
4. Past-life regressor
5. Tsuyokute New Saga
6. Again my life - this one is about law and isn't really an isekai but the protagonist returns back to the past so it's kind of similar
Also, similar to this is the concept of being reincarnated into a web novel or manga being completely aware of the narrative and using it to change the events which I'm also looking for
Examples:
1. Trash of the count's family
2. Omniscient Reader's Viewpoint - this one is one of my personal favourites I'd really like recommendations similar to this one
Any titles apart from these would be greatly appreciated, I'll be sure to check them out!

As a side note, Re:Zero is kind of similar to this as well since Subaru does go back to an earlier time so he is technically a regressor so something similar is also appreciated!
