A great theme is their relationship as friends who have known each other since childhood. Fanfictions could explore how they've supported each other through tough times, like when Sakura was bullied for her large forehead and Naruto was ostracized for having the Nine - Tails inside him. Also, their participation in village festivals and how they create memories together can be a wonderful theme.
One good theme is their growth as ninjas. They could be shown training under different masters and sharing their experiences. Another theme could be their role in diplomatic missions for the Hidden Leaf Village. It would be interesting to see how they interact with other ninja villages and represent their own.
Some fanfictions focus on their post - war lives. For instance, how they help the younger generation of ninjas. Naruto could be teaching them about the power of perseverance and Sakura could be teaching medical ninjutsu. This shows their positive influence on the future of the Hidden Leaf Village and their strong bond as comrades who have been through a lot together.
