I like INFP because Fe is one thing I haven't noticed in you, but I only know you through text, so the final call is yours. I like 5w4, too. Your typing has come down to the minor details, subtle judgment calls that don't come through if not face to face. So, at worst, you are still very close to the right one.
For me, mostly asking your opinion on the blank. Wings have really oscillated over life (dramatically!), but there can only be one victor.
