Best view I have seen in the park is a little further back from the statue there is a hump over the moat or something.. that is the highest elevation on Main Street/in front of the castle and seems to be the perfect place to watch the fireworks and the projection show from. You can really see everything from there!
FP+ for Wishes is really nice as well as it is in the rose garden and offset from the castle at a good angle. If you have kids it is nice to be able to spread out a blanket on the grass and get some time off your feet as well.
