So I found a thread talking about FIMfiction, and they happen to have a list of stories they recommend as a place to start,
I can personally say The Best Night Ever, Hard Reset, Mendacity, and Arrow 18 are all great fics, so the list is promising to me. Consider checking a story you haven't read, especially if it's in a genre you favor.
