Well, perhaps Naruto could use his ninja skills in the way Zhuge Liang used his military strategies. For example, Naruto might outwit his enemies in battles like Zhuge Liang did with his brilliant tactics in ancient Chinese warfare. He could set up traps and use deception, just as Zhuge Liang was famous for his empty city ruse.
One possible plot could be that Mikoto somehow survived and she takes Naruto under her wing. She trains him secretly, using her Uchiha knowledge to make him stronger. This could lead to Naruto having a unique set of skills that no one else has.
Well, one possibility is that Naruto resigns due to feeling burnt out from all the battles and political unrest in the village. He might decide he's done his part and wants a simple life away from the chaos.
Maybe Naruto discovers some dark secrets about his family that completely shatter his world view. For example, he finds out that his father was involved in some really bad things. This revelation makes him question everything he believed in and he becomes emo as a result. He might start wearing darker clothes, cutting off his hair, and his behavior towards others becomes cold and distant.
One possible plot could be that Naruto is wrongly accused of a crime he didn't commit. Maybe he was framed by an old enemy who wants to see him suffer. While in prison, he tries to prove his innocence. He could use his ninja skills subtly to gather evidence within the prison walls, and also make some unlikely allies among the inmates who start to believe in his innocence as they get to know him better.
In a 'naruto is a uchiha fanfic', a possible plot could be that Naruto is so inspired by the Uchiha that he tries to bring back the glory of the clan. He starts by trying to understand their culture and values better. He could try to convince the village to support the revival of the Uchiha name. This would likely involve him dealing with the political aspects of the village as well as any lingering grudges against the Uchiha. He may also have to face off against those who would rather see the Uchiha stay in the past, all while learning more about the Uchiha's unique abilities and trying to incorporate them into his own fighting style.
There are probably 'naruto is evil' fanfics out there. A possible plot could be that Naruto is influenced by some dark force. This force twists his perception of right and wrong. As a result, he starts to target his former friends and allies. He might use his skills to cause chaos in the ninja world, believing that the current system is corrupt and needs to be overthrown.
Obviously Naruto as Zhuge Liang would be the most interesting. He would bring a whole new dimension to the character, combining his ninja abilities with Zhuge Liang's strategic mind. But also, characters like Sasuke could be interesting. He could be like a rival general or a difficult ally, similar to how there were complex relationships in Zhuge Liang's time.
Romance of the Three Kingdoms was a classic Chinese novel. It told the story of Liu Bei, Guan Yu, Zhang Fei, and Zhuge Liang's conquest of the world during the Three Kingdoms period. The following are some stories about Zhuge Liang: Zhuge Liang went to Dongwu and proposed to Sun Quan that they should unite to resist Cao Cao, but Sun Quan refused. However, Zhuge Liang used his own wisdom and wit to successfully persuade Sun Quan to realize the plan to unite against Cao Cao. Zhuge Liang was resting in Wolonggang when he was discovered by Cao Cao's advisor Sima Yi. Sima Yi wanted to use Zhuge Liang's wisdom to fight against Cao Cao, but Zhuge Liang successfully avoided Sima Yi's attack and proposed a strategy to counter Sima Yi. After Liu Bei captured Jingzhou, Zhuge Liang went to visit Liu Biao, the herdsman of Jingzhou, and proposed a plan to help Liu Biao seize Jingzhou. However, Liu Biao didn't trust Zhuge Liang's plan, so Zhuge Liang couldn't successfully realize his plan. After Liu Bei seized Yizhou, Zhuge Liang went to visit Liu Zhang, the herdsman of Yizhou, and proposed a plan to help Liu Zhang seize Yizhou. However, Liu Zhang didn't trust Zhuge Liang's plan, so Zhuge Liang couldn't successfully realize his plan. When Liu Bei attacked Wu, Zhuge Liang proposed the plan of burning Red Cliff. He successfully burned Wu's fleet, allowing Liu Bei to successfully seize Jingzhou. These are some of the stories about Zhuge Liang, which show his intelligence and resourcefulness.

Perhaps Naruto gets corrupted by some dark force. It changes his personality completely. He might start seeing all the people in the Hidden Leaf Village as the source of his problems. He could remember all the times he was ostracized as a child and now blames everyone for it. So in the fanfic, his hatred for everyone grows as he views the world in a new, darker light.
