Well, perhaps in the fanfiction, Naruto is reanimated with some new and strange powers. He then uses these powers to help the Hidden Leaf in ways he couldn't when he was alive, like being able to instantly transport people to safety during an attack. He might also have the ability to communicate with the spirits of the past Hokages more directly and gain their wisdom.
One interesting plot could be Naruto coming back reanimated and having to team up with his former enemies who are also reanimated to fight a new, greater threat. This would turn the whole idea of enmity on its head.
One interesting concept could be the reanimation of characters in new and unexpected ways. For example, seeing how a reanimated Naruto might interact with his old friends and foes with a different perspective. Maybe he has new powers or abilities due to the reanimation process.
One interesting plotline could be Naruto coming back reanimated and having to face new enemies that his old friends can't handle alone. His reanimated state might give him unique powers or abilities that change the course of battles.
One interesting plot idea could be Minato's reaction to seeing how Naruto has grown. He could be both proud and a bit sad for missing out on so much of his son's life.

Maybe he could also interact with the other characters in Konoha and share his insights from his time as Hokage.
One common theme is the exploration of family bonds. Naruto has always longed for a family, and when he reanimates them, it delves deep into how those relationships can be rebuilt and strengthened. Another theme is the idea of second chances. His family gets a chance to be part of Naruto's life again, and Naruto gets a chance to experience a family upbringing he missed. It also often includes themes of sacrifice, as Naruto may have to sacrifice something in order to reanimate his family, whether it's his own energy or something else.
If Naruto is reanimated by Edo Tensei in fanfiction, it could lead to a very different story arc. Naruto's abilities like his Rasengan and Sage Mode could be enhanced or distorted in this reanimated state. The story could explore how the village he loves so much reacts to his reanimation. His relationships with other characters would also change drastically. For example, Sasuke might be conflicted about fighting a reanimated Naruto. Also, the one who performs the Edo Tensei would have a difficult time controlling Naruto if his willpower remains as strong as it was when he was alive.
One interesting plot could be Naruto coming back with new and enhanced powers. Maybe he has a special connection to a new chakra source that was unknown before his revival. This would make him even more powerful and able to face new threats that emerged during his absence.

He could use his ninja skills to help Candace deal with the pesky brothers who are always causing trouble.

Well, in some 'naruto is hokage fanfiction', there might be a plot where Naruto discovers a long - lost secret about the Hokage position.

His kids might get involved in some dangerous situations that he has to handle while still leading the village.
One interesting plot could be Naruto as a girl facing unique challenges in the ninja world.
