We’ve toured most of the California schools you have listed. I’ll give you my perspective but take it for what it is worth. I don’t know you and you don’t know me.
UCSB and UCSC are very very different. Calculate your UC GPA to get a better perspective of your admission chances - 10th and 11th grade only with a max of 8 semesters (4 yrs) of AP coursework. https://rogerhub.com/gpa-calculator-uc/
UCSC is more bohemian and is in the woods, not on the beach. It is in Northern California so is more rainy and cold that UCSB. When we visited, we didn’t get the feeling that UCSC was organic, healthy bohemian but more mountain men, Red Bull bohemian if that makes sense. It has a college system so the campus is divided into 10 residential colleges which some prospective students may like and some may not.
UCSB is more of a beachy/party scene. Although the university is trying to get the partying under control, the school still has that reputation and attracts kids that are interested in that lifestyle. Many members of my family have attended UCSB and loved it. I think you just need to find your group of friends and have a solid, secure sense of values and priorities when you enter. I think UCSB might be more of a reach with your 28. Did you study and prep for the ACT? If not, maybe you can study a bit over the summer and bring it up.
USD is a beautiful campus located on a cliff overlooking San Diego. The kids seemed happy, healthy, social and engaged. It is a small campus and very Roman Catholic. They give scholarships to anyone who attended Catholic HS. There are at least two churches on the campus. It was a little too religious for our family but might work for you.
Santa Clara is Jesuit and there is less of an emphasis on religion that USD. It is a very clean medium size campus. The church on the campus is a California Mission. It is located in San Jose (Northern California - colder than San Diego or Santa Barbara). It is right next to Google, Facebook, Ebay, Apple and a bunch of other tech type firms. There isn’t much of a college community surrounding the campus before you get into the city of San Jose. Santa Clara wants you to show “demonstrated interest.” They know that not everyone can travel to visit their campus. I would call the school and explain that you live out of state and won’t be able to visit. They might set up a phone or Skype interview. Be prepared as they are logging your call and are taking notes on the type of person you are. Have well researched questions ready before you call.
USF - Smack dab in the middle of San Francisco. There isn’t a college community around the campus but if you want to live in the heart of San Francisco, it is a good choice. We didn’t tour the campus so I can’t tell you much about the religious side or values on campus.
We haven’t toured UW or Oregon but UW is a big campus in a cold and rainy climate where it snows. Your scores are a little low for UW so, if you are looking for something warmer, I would eliminate that from your list. Oregon is also more cold and rainy compared to your So Cal schools but not as bad as UW. The town around Oregon is a college town so, if that is what you are looking for (compared to Santa Clara, USF, USD) it might be a good choice. Oregon is Pac 12 and has a lot of school spirit.
If you are looking for Catholic schools in warm weather, have you looked at Loyola Marymount University (LMU)? It is a beautiful campus with a lot of school spirit. Everyone I know that has gone there has loved it. http://www.lmu.edu/
As far as med school, if that is your dream, don’t give up on it. Everyone grows and matures at different rates and a 28 doesn’t automatically spell doom. There are hundreds of med schools with different admission requirements. That said, if you want to go into health care, be open to allied health professions as well - dentistry, optometry, physical therapy, occupational therapy, speech therapists, physicians assistants, chiropractics, osteopaths, etc.
