Having gone through this process twice, the second time just now with my college senior, here’s my advice:
A 3.8 GPA with good rigor, 35 ACT, top 15% and a range of ECs including one where you have achieved national recognition are fantastic. However, I know many such students, including my own kids, and when you are reaching high, there is no way to predict. You might get lucky and get into several. You might get shut out from all.
The only admissions safety I see here (perhaps) is Pepperdine. Would it be a financial safety?
UIUC and U Washington are matches/low reaches for OOS (out of state). They will also be expensive. The maximum OOS merit from U Dub is about $10K (purple & gold scholarship)
Are there any Cal States you would consider?
As a California resident, you are eligible for Western Undergraduate Exchange (WUE), which offers reduced OOS tuition at many western state public universities. Some of the better ones are Washington State, Western Washington, U of Arizona, Arizona State, U of Utah, and U of New Mexico. Even without WUE, your chances of getting significant merit money are pretty good at all of these (minus Washington State). Many of these have fine honors colleges, especially the Arizona schools.
What are you looking for in a school? You have everything from small women’s colleges to church affiliated schools (both Catholic and Church of Christ) very large state flagship universities and everything in between. This is not a bad strategy. Your needs and preferences may change from the time you apply to the time you enroll at a college. Aside from urban/suburban location, I don’t see a unifying theme.
I hope this does not seem harsh. You have impressive accomplishments. However, elite college admissions is more competitive than you can imagine, especially given the surge in applications due to COVID-19 and test optional policies. This year, the acceptance rate at many top schools was in the single digits. Do not underestimate the effect on your morale if you were to get a string of rejections because your list was reach heavy. Apply to some that you particularly like, maybe your ED possibilities as they are probably your favorites. But be sure to have plenty of true matches and safeties that your family is willing to pay for.
