Another possibility is Naruto traveling back to his own childhood days. He could mentor his younger self, teaching him advanced jutsu and wisdom he's gained over the years. This would make his younger self much stronger much earlier, and might also change how he interacts with Sasuke. For example, he could help his younger self better understand Sasuke's pain and prevent some of their earlier conflicts.
During the seventh time travel, Naruto could develop a deeper understanding of the power of friendship. Maybe he meets some old friends in a different context during his travels and realizes how important they are in a whole new way. For example, he might see how his friends' small actions in the past had a big impact on the future. This could make him more appreciative of them and also more determined to protect their relationships. He could also grow in his ninja skills as he has to adapt to different situations and opponents in the past, using his current knowledge to his advantage while also learning new techniques from the past.
If Naruto changes something major in the past, it could disrupt the timeline. For example, if he prevents the Uchiha massacre, Sasuke's path would be completely different. He might not have the same drive for revenge, which could mean he doesn't leave Konoha. This would change Naruto's own growth as a ninja, as Sasuke was a big part of his motivation to get stronger.
One interesting plot twist could be that Naruto travels back in time and discovers that the Hidden Leaf Village was founded on a much darker secret than he ever knew. This changes his perception of the village's history and his role in it.
