You will definitely be admitted to Metro. Metro really has a lot of financial support.
If you stay instate, you’ll get the Colorado subsidy, which is about $77 per credit. It goes a long way at a public school, not so far at DU or Regis. However, both DU and Regis have merit scholarships. DU has a housing allowance. DU is on light rail so easy to get to. I don’t think Regis is yet, but it is on bus routes.
If you want a bigger school residential experience, you might look at Mesa in Grand Junction.
CSU also has a Native American program with financial aid.
An OOS school that might work for you is Wyoming. My daughter attended and there are a lot of Colorado kids there because, after merit scholarships, it is usually cheaper than instate at Colorado. My daughter paid about $16k per year, and most was covered by aid and scholarships. Housing is very inexpensive. She’s returning for grad school next year and found a room in a house for only $400/mo, including utilities.
If you’re happy with Metro, it really offers a lot of opportunities (my daughter took three classes there one summer and we thought it was great). Light rail is so convenient. They have sports (Div 2), Greek life, lots of clubs. It’s right in the heart of the theater district, professional sports nearby, government offices just down the street for internships and experience. My daughter will look into Metro’s study abroad in France next year (it’s been cancelled the last 2 years because of covid) as it looks like a good way to learn French quickly after being away from it for 3 years (she needs it for grad school).
Don’t worry. Just decide what you want and go for it.
