One common theme is the bridging of different eras. Since Sakura is from a much later time than Hashirama, fanfictions often explore how their different knowledge and values interact. For example, Sakura's modern medical knowledge vs Hashirama's more traditional ninja skills.
Sakura is a very intelligent and hard - working character. Hashirama is creative and has a great sense of leadership. In a fanfiction, their personalities could create an interesting dynamic. Sakura would likely ask Hashirama a lot of questions about the old ways of the ninja world, and Hashirama would be eager to answer. Their interactions could also lead to new ideas for both of them. For example, Sakura could come up with a new way to use her medical ninjutsu in combat based on Hashirama's combat strategies, and Hashirama could think of new ways to improve the village's medical facilities based on Sakura's knowledge.
Sure. One popular sakura haruno hashirama senju fanfiction is 'A New Bond'. It explores a unique relationship between Sakura and Hashirama in a world where the boundaries of time are blurred.

One plot idea could be that Sakura, through some kind of time - travel jutsu, ends up in Hashirama's era. She uses her medical ninjutsu knowledge to help in the village's early development. Another could be that Hashirama's spirit somehow gets connected to Sakura in the modern era, and he gives her advice on how to handle difficult political situations in the Hidden Leaf. A third idea is that they meet in a dream realm where they exchange ideas about chakra control and nature manipulation.
