You can find a few bits of similar topics discussing this if you know the term. I’ll link some
Bit of general advice, don’t write from a certain Point of View because “why not?”. Bad idea. There’re differences between going first person, 2nd, or 3rd. You can find them in the topics I linked.
Using a certain POV presents some kind of “distance” between the reader and the MC. Using different POV can lead to big difference in the experience the reader… experiencing. So, yeah, with 1st person, you put the reader inside the MC’s head. You can describe the thought process of the MC, their inner feelings, their “anima” if you’re going the Jungian territory, so on. The reader will only know informations the protagonist know. This is a very specific thing to write and the reader may either like it or very dislike it. Best genre would be horror/thriller.
2nd person is the default in Interactive Fiction Realm. Pretty explanatory. The first generation of IF is not titled Choose Your Own Adventure books without reason.
3rd person is the “big approach.” As opposed to 1st person, you can be omniscient and tell the reader what’s going on with the world where the protagonist not necessarily know. Or you may put the reader in the seats of a theatrical stage and take them to the wild ride that is the show the stage performing. Kinda stretching the example, but you get the gist.
