Besides Disney and Spongebob, my 11-year-old has also seen Anastasia, Phantom of the Opera, Wicked, and Once On This Island. She loved all of them. Once On This Island is unique because the immersive set is so different from anything else. It's also only about 90 minutes with no intermission, so much shorter than most shows (which can be easier for kids). I don't think you can go wrong with any of the shows mentioned so far.
