Likelihood of admission to these highly selective schools hinges on details that we as online commentators don’t have but about which you likely have good visibility.
As to location, California residency for a list of highly selective schools, many of which are on the East Coast is probably a neutral.
As to major, Econ is a popular choice. Possibly a slight negative in terms of “diversity” as you’ll be compared against a big pool of future Econ students.
GPA: Highly variable. 4.0 / 4.9 carries much different meanings at different schools. At some schools, a 4.0 carries a very high likelihood of admission to one of the colleges you listed. At others, a very low likelihood. Highly selective colleges have dossiers for each high school including data on prior applicants and previously admitted students including GPA data. Your high school may be able to provide you with a spreadsheet of GPA’s / SAT scores vs. admission statistics that would be much more accurate in terms of chancing than someone here saying “4.0? Pfft whatever” which is so unfortunate given the effort, consistency and talent it takes to get that 4.0 at almost any school.
HS coursework looks good as to rigor. Congrats on exemplary performance on your AP’s especially the very tough European History, English Lang. Difficult 5’s there. You are an excellent student.
Awards: Nice to see a breadth of achievement, probably not a standout at the schools you applied to, but you are showing a breadth of intellectual curiosity - and achievement.
EC’s - Difficult to evaluate your research with the Columbia professor. Might be a slight bump for Columbia. Otherwise, very strong and broad involvement with good leadership and some instances of “impact” in your community. You might face some assessments that there should have been more focus and less breadth, but not everyone has the gifts, opportunity or desire to become the world’s best snare drum player or javelin thrower. Your breadth of activities should serve you well in becoming a very interesting and engaged adult (arguably more than the javelin thrower).
Overall, your actual chances depend most on your high school and its history with these colleges. If students like you, with your grades, scores and activities end up at T20’s (which one might assume given your college list) then you probably have a very good chance. If your stats were at Harvard-Westlake, TJ or Stuyvesant, that would be a lot different from the same stats at many public high schools.
Without a clear hook and with “all arounder” EC’s, you are in the company of many if not most high achieving students nationwide. Yours is an application where essays and your letters of recommendation as well as support from your school can be the difference. If you are in a position to have your guidance counselor pick up the phone and call University “X” and support you, that would likely be welcome information to the College.
Still, a few schools (not that rankings are accurate) but roughly in the 20-40 USNWR range as safeties would be wise.
