Congratulations on your achievements.
I can’t chance you, of course both Harvard and Princeton are reaches. Are you going to apply to Harvard SCEA?
I would also consider applying to Dartmouth, if it appeals to you. They have an institutional goal to increase Native American student enrollment.
Is CU Boulder affordable? They likely won’t provide much FA for you. Run their net price calculator to get a cost estimate (you should do that at all the schools on your list).
Good luck.
