Well, a really interesting plotline could be Obito trying to make Naruto see the world from a different perspective. Since Obito had a very different view of the ninja world due to his past experiences. He might try to make Naruto question the traditional values of the Hidden Leaf village. This could lead to Naruto growing in a whole new way, both as a ninja and as a person. He could also introduce Naruto to some of his old allies or enemies, which would open up new story arcs and character developments.
One possible plotline could be Obito teaching Naruto some unique jutsu that he learned during his time in Akatsuki. For example, he might show Naruto how to use certain space - time ninjutsu in a different way. Another could be Obito helping Naruto understand the Uchiha clan better, given his own Uchiha heritage.
In some 'Obito raises Naruto' fanfictions, Obito might take Naruto on a journey to explore the secrets of the ninja world that are not commonly known. This could involve visiting ancient ruins or meeting with reclusive shinobi. He could also train Naruto to be more stealthy and strategic, as Obito was known for his cunning in battle.
