I am studying photography, how can I know what photos are suitable for me?

This is hard to say. There are two answers:

1. What do you have to shoot? For example, if you are a journalist, you need to shoot current affairs news. If you are a photography studio You need to take photos of people and wedding dresses;

2. If you don’t have any utilitarian purpose, you just like it, then it depends on which direction you prefer, such as landscape, people, macro, etc.
