Be patient. I have 25 years higher-ed admin experience. There are a few thousand highly qualified minority students that apply to 10 to 15 or more institutions each. Their high school advisors tell them to do this to find the best package. They will typically get accepted to every school they apply for. Once these folks pick schools, the waitlists will open up. We see it every year. There is a still a good chance you will get into a top school. If you truly have a perfect ACT, you are one of about 4000. You are an elite student and will be in demand once other applicants start making decisions.
I have sat in many admissions meetings over the years. Here is how it goes. First, any elite minorities are automatically admitted. The athletes, musicians, or other students with exceptional talents are admitted if they meet a low minimum standard and are on a list given to the committee by the athletic department, or other university entity. Students with ties to the right people at the school are on a different list and are also immediately admitted. Children of school employees are admitted as long as they meet a low standard. Children of prominent donors are admitted at that low standard. Children of legacies are then admitted (not a sure thing like it used to be). Next, special circumstance applicants are admitted (handicapped, international from impoverished areas, etc...).
After all of these groups are taken care of, slightly less qualified minorities are admitted. (note - of all minorities we accept, only about 8-10% actually matriculate). Finally, at this point, things open up to everyone else. As for the process of how nearly identical high quality applicants are chosen...well...it is unscientific and pretty random. Schools like to geographically diverse so applicants for low population states have an advantage. Committees like home school kids because they are good citizens on campus. How impacted your intended major is will matter. Committees will look at your social media (if you are a partier, you will not get in). Yes...schools will look for political leanings on your social media. This is very important to some committee members. Extra curriculars and interviews are pretty much never discussed. Bad interviews only happen in movies and extra curriculars could all be made up and often are.
