Well, often there are storylines involving the training of new shadowhunters. They face challenges during their training and form strong bonds with their mentors or fellow trainees. Some fanfictions focus on a particular character from the original and give them a backstory that wasn't fully explored in the official work. For example, a side character might be given a whole adventure where they save the day in their own unique way.
A 'found family' trope is quite common. Characters who were alone or estranged in the show form a close - knit family in fanfiction. For instance, Henry might bring together different characters who then become his new family.

Also, a story about Belle teaching the other residents of Storybrooke about the power of books and knowledge could be really engaging. After all, she has a deep love for books.
Family relationships are a big theme. Some fanfics focus on the family dynamics between characters like the Charmings and their descendants.

One popular storyline could be Merida teaching Macintosh some of her archery skills. Since Merida is a skilled archer in her own right, she might show Macintosh how to properly hold a bow and aim for the target. Another could be them going on an adventure together through the Scottish Highlands, facing magical creatures and solving mysteries along the way. It could also involve Macintosh getting into trouble and Merida using her wits and courage to get him out of it.
Another common one is relationship - centric storylines. Writers often explore how Emma and Hook's relationship develops further, like dealing with misunderstandings or facing challenges together that strengthen their bond. It could be something as simple as a family member not approving of their relationship at first and how they overcome it.
