Naruto's power of the Nine - Tails would be a major factor. In the past, the Nine - Tails was feared and hunted. If Naruto shows up with the power under control, it could change how people view the beast. His chakra reserves, which are huge because of the Nine - Tails, could allow him to perform feats that were previously thought impossible in the past, like quickly rebuilding a village or fending off a large - scale invasion on his own.
One possible plot twist could be Naruto changing the past in a way that completely alters the future relationships. For example, if he prevents a certain event that led to a character's death, it could change the whole dynamic among the characters. Another twist could be that Naruto discovers that the past is not as simple as he thought, and there are hidden forces at work that he didn't know about in his original timeline.
Often, Naruto is sent back to a time when he can prevent a tragic outcome or gain crucial knowledge. It could be to the time before his village was attacked or when a key character made a fateful decision.

Madara Uchiha could also be a main antagonist. If Naruto goes back to a time when Madara was still alive and plotting, Madara would surely oppose Naruto's attempts to change the future. He has his own grand plans for the world and wouldn't let Naruto interfere easily.
One major theme is change. The whole idea of time travel implies change. Fem Naruto aims to change the past, which in turn changes the future. This can lead to exploring different possible futures for the Naruto universe. Additionally, the theme of love often pops up. It could be platonic love for her friends or a different kind of love interest that emerges as a result of her time - traveling experiences. She might find herself falling for someone she didn't expect because of the new circumstances in the past.
One idea could be Naruto going back to the time when the Uchiha clan was still intact. He could try to prevent the massacre by changing certain events or by influencing key people. Another plot could be him traveling back to his own childhood and using his future knowledge to become an even more powerful ninja earlier, like learning advanced jutsus much sooner.
In the past, their relationship could be more complex. Kakashi might be suspicious of Naruto's sudden appearance and his knowledge from the future. Naruto would have to prove himself to Kakashi. However, as they work towards a common goal, like saving Konoha from a threat in the past, they would gradually build trust. Their relationship could also change in terms of how they interact with others in the past. For example, they would need to pretend to be normal villagers or ninjas from that time, and this new situation would impact how they relate to each other.
