One great 'Female Naruto Shikamaru AU' fanfiction is 'The New Path'. In this story, the female Naruto has a completely different dynamic with Shikamaru. It explores how their relationship might develop in an alternate universe where Naruto is female.

For the older generation like the Third Hokage, watching an AU fanfiction might make them regret some of their decisions in the original story. If they see an AU where they handled things differently and it led to better outcomes for the village and its people, they might feel a sense of remorse. This could then affect how they interact with the younger generation. They might be more open to new ideas and less set in their ways, which in turn could improve their relationships with the likes of Naruto and his friends.
Well, one possibility is that the 'new' Naruto, who is actually the original Naruto in a different role, could change the course of events in the Hidden Leaf Village.

In a 'naruto is in a au harem fanfic', aside from the obvious choices like Sakura and Hinata, characters like Temari could be in Naruto's harem. She's from another village and has a strong personality. Her presence would bring in an element of cross - village relations. Karui is also a possibility. She's feisty and has her own set of skills. And then there's Kurenai, the jonin. She could be an interesting addition to the harem, with her experience and calm demeanor.
One possibility is that Naruto enters an AU where chakra doesn't exist. Instead, there are other forms of power. He would have to learn how to use this new power from scratch. Also, the relationships between different ninja clans could be very different. Naruto might end up making new alliances and enemies based on this new dynamic. This could be a great opportunity for character development as he faces challenges that are completely different from what he's used to in his original world.
Naruto could be a tech geek in a modern AU, working on the latest software developments. Hinata might be a fashion designer. They could meet at a tech - fashion event where Naruto is presenting some new wearable tech and Hinata is looking for inspiration for her new collection. Their relationship would be a blend of two different worlds, with Naruto being amazed by Hinata's creativity in fashion and Hinata being interested in Naruto's technological prowess.
In this type of fanfiction, the plot might develop in a way that Naruto tries to fix things he previously thought were okay.

This would then lead to him facing opposition from the traditionalists in the village, creating a lot of conflict and drama in the story.
In a modern AU, Naruto as a boyfriend would be an adventure. He'd be super enthusiastic about trying new things. He'd introduce you to his friends, who would become like a second family. He's not the most sophisticated, but his genuine nature makes up for it. He'd probably text you a million times a day just to check in and tell you how much he misses you when you're apart.
