First, get there before opening. 9 AM open means they’ll let people in by 8:30 AM. I always like starting in Fantasyland and, if you haven’t yet, the new Snow White is a must see.
I would plan Galaxy’s Edge around the time you get a RotR boarding pass and do Indy > Pirates > HM > Splash early based around your boarding pass. Space is also a good option to hit early on in the day or later in the evening.
I’m partial to a Big Thunder sunset ride, so no thoughts on when you should hit that.
