I write a lot of stories and I use many styles of writing. These are some:
1st person view/P.O.V.s - I use this a lot. For my story, FNaF Fanfiction, I have all the animatronics have a P.O.V. (Position of View).
3rd person view - I sometimes use this one for some stories.
The Fourth Wall - I have to admit, sometimes I break the fourth wall on some stories. It's basically when a character in a story is almost talking to the reader, for those people who don't know.
2nd person view - I am horrible at writing these. I like to read 2nd person view stories but I definitely can't write them. These are stories that include and interact with the reader.
Of course, there are many more styles that I am not listing, but these are my reviews on some of them.
