Curate, connect, and discover
So I saw a post about this recently ( i will track it down eventually), but i wanted to illustrate my point (literally).
For Horror, romance etc. I generally use 1st person, because it helps me portray emotion better. As in the illustration, it helps with suspense. You aren't the all-knowing 3rd person and can be surprised. You feel the emotion of the characters!
For anything that isn't emotion-based and relies heavily on description and being able to see further than one person can (sci-fi, for example) 3rd person is the standard.
tl;dr: for emotion, you use 1st person, for description, you use 3rd person.
