Well, it really depends on the writer's preference in the fanfiction world. If the writer wants to focus on the initial crush Naruto had on Sakura, they might make Naruto and Sakura get together. However, if they are more into the idea of Naruto finally realizing Hinata's true feelings and reciprocating, then Naruto will be with Hinata.
Well, it could be Hinata. In the original series, they have a strong connection, so in a fanfiction, it's quite possible that Naruto would choose her to propose to.
Geralt ends up with Yennefer. Their relationship is complex and filled with passion. They have a deep connection that has been through many trials and tribulations throughout the story. They care for each other deeply despite their differences and the various challenges they face in the world of the Witcher. It's a relationship that is central to much of the story's emotional depth.
