I have never had a hamburger or nuggets at a QS in over 30 years of going to WDW. Every park has options other than that. Our favs:
MK: Pecos Bills, the servings are big easily shared if you want and the toppings bar is great.
AK: Haven't tried the new on in Pandora but there are loads of options in the new market by Africa and our favorite is fried rice from Yak and Yeti.
HS: There are plenty of options in the area just before ToT, we actually like Backlot Express.
Epcot: The sky is the limit in WS.
Resort area: BW has a number of good places, we liked Big River Grill. Just about every food court at every resort has loads of options.
I can't help you with water parks, we don't do them.
