OP, I think you have a shot at all your reaches as an “average excellent” student based on the info you have shared. That means your academics (grades, rigor and test scores) and EC’s get you past any initial hurdle. The decision will be driven by your LoR’s and essays and how the AO’s picture you fitting in their schools.
If we were still living in California, I would not encourage my kids to apply to big out of state state schools, even great ones like UMich because the California system is so good and affordable. The exception may be well regarded honors type programs which allow you to study in a “small” community in the midst of a huge state university.
You should also realize that there is a divide in opinion on whether which undergrad program you go to matters for T14 law school admissions. While it is true that elite law schools like Harvard have students from a variety of undergraduate programs, a large portion of the incoming class come from about 20-30 colleges with a lot of onesis from lesser known schools. Of course this leads to a question of causation vs correlation. Do students from HYP get into Harvard Law in such numbers because they went to HYP or is it because they are probably good students and test takers to begin with. I think it is a bit of both. There are threads that debate this exhaustively in CC, and I don’t want to rehash the argument other than to say there is a difference of opinion among respected posters.
