What could be the plot of a 'Naruto marries Itachi' fanfiction?

Well, it could be about Naruto learning Itachi's unique jutsu. For example, Itachi's Sharingan techniques. Naruto might start to understand the Uchiha's way of fighting and incorporate it into his own style, which is mainly based on his Rasengan and shadow clones. It could also involve Naruto learning about Itachi's past and the secrets of the Uchiha clan, which would give him a new perspective on the ninja world.

One possible plot could be that Itachi, seeing Naruto's potential and his importance for the future of the Hidden Leaf, decides to secretly train him.

Naruto's positive energy and determination could blend well with Itachi's strategic mind and powerful jutsu.

Perhaps Itachi would teach Naruto some advanced jutsu techniques. Naruto is known for his Rasengan and later on Sage Mode, but Itachi could introduce him to more subtle and strategic ninjutsu.
