One possible prep school 2019 novel could be 'The Secret History' by Donna Tartt. It has a very academic and somewhat dark atmosphere set in a college - which has similarities to a prep school environment. It delves into the lives of a group of students and their complex relationships.
The mean elf could be redeemed through acts of kindness. If it starts helping the other elves with their tasks in Santa's workshop, that would be a start.
The setting in a novel provides context. It gives a backdrop against which the story unfolds. In a historical novel, the setting of a particular era, like the Victorian England, determines the social norms, the fashion, and the technology available, which all play a part in the plot. Without a proper setting, the story would seem disjointed and lack authenticity.

Well, a 'danger guy' story could be about a daredevil who loves extreme sports. For example, there's this guy who loves rock climbing on the most difficult and dangerous cliffs. He once got stuck on a ledge during a storm but managed to hold on until help arrived. His skills and determination were truly remarkable.
One way is to look at the sources. Nonfiction usually cites real sources. Fiction doesn't. For example, a nonfiction book on World War II will have references to historical archives. A fiction novel about the war might be more about a fictional character's experience.
Use memes. There are countless memes out there that can be applied to different situations. Just find one that suits your mood or the story you want to tell. Also, add some silly sound effects to your videos. For example, a cartoonish 'boing' sound when something unexpected happens.
There are various popular ones. Some might focus on exploring new relationships between existing characters. For example, a fanfiction could be about a character from one Star Trek series interacting with a character from another in a unique adventure that was not part of the official canon. Another popular type could be those that expand on a particular episode's events, adding more depth and different perspectives to what happened.
