One common theme is friendship. Their deep bond is often explored, like how they support each other through tough times at Hogwarts. Another theme is adventure. They are usually on some sort of quest, whether it's finding a lost magical artifact or solving a mystery. And love can also be a theme, sometimes in a platonic way, showing how much they care for each other, and sometimes in a more romantic sense, imagining a different kind of relationship between them.
One great 'Harry and Hermione' fanfic is 'Harmony's Path'. It explores their relationship in a post - Hogwarts world where they work together to solve new magical mysteries. Another is 'Hermione's Choice' which delves into an alternate universe where Hermione has to make some tough decisions regarding her friendship with Harry.

Yes, it could be normal. Since Hermione is an important character in Harry's life, he may be interested in seeing how others perceive her in fan - created stories. It could be like how we might be interested in what others write about our friends or people we admire.
Power dynamics also play a role. The female characters in the harem might have different levels of power, magical or otherwise, and how Harry relates to them in that context is often explored. For example, a powerful witch in the harem might have different expectations and interactions with Harry compared to a less powerful one. And also, the idea of loyalty within the harem is explored. How the characters remain loyal to Harry and to each other is an important theme in these fanfics.
