One possibility in the 'Naruto banished joins Akatsuki' fanfiction is that Naruto's presence would create a lot of internal conflict. Some members of Akatsuki might see him as a threat to their plans, while others might be intrigued by his power and ideals. Naruto, on the other hand, might be constantly torn between his loyalty to the Hidden Leaf (even though he was banished) and his new position in Akatsuki. He could also try to use Akatsuki's resources and connections to find out more about his own past and the secrets of the ninja world that the Leaf Village might have been hiding from him.
In this kind of fanfiction, Naruto might face a whole new set of challenges in Suna. He could bring his unique skills and determination to Suna. Maybe he'd form new friendships with Suna ninjas and help improve Suna's overall strength. He could also share his knowledge about certain jutsus that are unique to Konoha.
Well, he could gain new and powerful abilities. Maybe he discovers a hidden bloodline within himself or through some encounter related to the new bloodline he joins. He might use these new powers to prove his worth to those who banished him.
Sasuke could be an ally. Despite their past differences, Sasuke might see the injustice of Naruto's banishment and decide to join him. He could bring his powerful Sharingan skills to the new village. Also, some of Naruto's old friends like Shikamaru or Choji might secretly support him and provide resources or information. They could be like undercover allies still within the old village but helping Naruto's new village in various ways.
In this type of fanfiction, Naruto could be banished because of a conspiracy within the village. When he starts his new village, he may attract ninjas who are tired of the old - fashioned and corrupt ways of the existing villages. His new village could be a haven for those who want to practice their ninjutsu freely and without judgment. He might also establish a unique training system that combines his own experiences and the skills he learned from different masters, creating a new generation of powerful and morally upright ninjas.
The main antagonists could be some of the conservative Iwa ninjas who oppose Naruto joining their village. They might see him as a threat to their traditional ways and values. Also, there could be some rogue ninjas from other villages who target Naruto because they see him as an easy target now that he's in a new and unfamiliar environment.
One possible plot development could be Naruto facing initial hostility in Iwa. Since he's from Konoha, the Iwa ninjas might be suspicious of him at first. But Naruto, with his determination and unique skills like the Rasengan, could gradually earn their respect. He might also learn new jutsu unique to Iwa and form new alliances, perhaps even finding a way to bridge the gap between Konoha and Iwa in the long run.
Well, one possibility could be that Naruto is banished from Konoha due to some false accusations. When he joins Iwa, he might start learning their unique jutsu and fighting styles.

But as time passes, he proves himself and becomes an important part of Iwa, maybe even leading some missions against common enemies of both villages.
Well, one possibility is that Naruto could learn a great deal from Itachi. Itachi is highly skilled and intelligent. Naruto might gain new jutsu or a different perspective on the ninja world. They could form a powerful duo, taking on enemies that Naruto couldn't face alone before. Maybe Itachi would teach Naruto some of his unique genjutsu skills, which would make Naruto an even more formidable opponent.
He might face a lot of challenges at first. People in the new village may be suspicious of him because he's an outsider. But Naruto's determination and his ability to make friends could gradually change their minds.
