Alt-F4 is the canonical shortcut for closing a window

F2 is the canonical key for renaming

F5 is refresh

F11 is fullscreen

F1 is for help but admittedly I don't use that a lot

I can't think of a very frequent, standard use for the other keys. So I can't really disagree with having so many F keys being kinda unnecessary. But I'm happy to have them and they never bothered me.
