I agreee with @lookingforward.
Do you know how to read schools’ CDS? The Common Data Set shares the weight that different schools put on different categories. Geographic region is very unlikely to hold the same weight as test scores at any school. Test scores for homeschoolers tend to hold more weight as a filter. Your test scores are just not at a selective-competitive level. If they were 33+, then the level of competitiveness might increase to the realm of maybe possible vs. unlikely.
For example, Look at pg 8 of Smith’s CDS: https://www.smith.edu/sites/default/files/media/Office%20Images/Institutional-Research/Smith%20College_Common%20Data%20Set%202018-2019_Version%201.pdf
Geographic region is “not considered.” On pg 10, 82.8% have an ACT score of 30-36 with 53% in that range for math.
Your ECs sound fine, but ECs are considered after the initial academic threshold hurdle is surpassed.
Based on your ECs, MOOCs, AP tests, etc, it is hard to imagine compelling “extenuating circumstances” that bridge the gap that exists. Your education will be viewed as privileged b/c you had the freedom to pursue any academic level of coursework desired.
I am not writing this to be a dream killer, just to share what I know from helping my kids apply to college and how admissions has worked. I think that if you step down a notch in your goals, you will find a lot of schools where you will be a strong candidate.
BTW, you didn’t answer my question about budget. Do you have any financial constraints or is money no object? If you are going through this process without parental help, you need to be aware of costs and ask your parents exactly how much $$ you have.
