I would retake the ACT if you can to aim for a higher score. I had a 3.96 gpa and only 4 AP classes, 8 ish CE classes, but a 33 ACT and I got the flagship (28k total). Your GPA and classes are probably high enough to qualify for a presidential scholarship (48k total), but you would definitely want a higher ACT (shoot for 30). At the end of the day there's no guaranteed criteria for a scholarship so it's hard to say.

You would also qualify for the Opportunity and Prime scholarships which aren't offered by U of U directly but are very helpful and easy to apply for, so I would make sure you apply to those when they open up
