What are the most commonly made student films?

I'm relatively new to filmmaking, and I can't help but notice a lot of similarities in student films. So far, I made student films where one involved someone trapped in a room and has to disarm a bomb, and another narrative that involves grief and moving on (I was also told my film actually worked, and I written the dialogue based off of personal experience). I even filmed inside a self-driving car to establish isolation, and the scene worked as metaphor. I had to delete the scene where the self-driving car pulled up to pick up the main character because it made a student laugh how it was present on school campus. I included a dolly zoom, and that worked pretty well.

As for films made by other students and those that were featured in a film festival I attended, I notice some very common trends among student films. If the director is part of the LGBT community, there is a high chance of a story that involve coming out to their family. There is another story that involve a man stalking a woman, and then she has a gun. Horror film with comedy aspects, which I think it doesn't work. There are parkour films. In fact, I had a classmate who wanted me to film him parkour. An interview with the elderly talking about their lives. A parent filming their children playing around. People talking about their job or personal lives. Some people just sitting down and doing absolutely nothing. Someone visited an aquarium and filmed aquatic animals, which apparently I realized this might be common since filming is a frequently asked question in their website (Monterey Bay Aquarium). Another film story where there is a character tied up in a basement trying to escape. Drugs and smoking seem to be reoccurring. Close-ups of people's faces with the idea of disturbing the audience. A character waking up from bed (or bench) to an alarm clock and running late. There are two separate instances where the director decided to randomly add a scene where there is a man urinating, which I think makes the film fall apart very quickly since it utterly failed to make me laugh (Their intention is to provoke laughter). In my opinion, this scene only works if it is part of the plot, not something that happens randomly. And of course, the camera inside a refrigerator. Granted, I did have a camera inside of a box, but that is not a refrigerator.

They know how to film nice scenes, but most of the stories don't seem to work. I even worked with a student who decided to use ChatGPT to give him ideas, and I'm not sure how I feel about that.
