One thing about merit - when your student “outperforms” the rest of the student body, that’s where you get merit. Some publics (U or Arizona, Washington State) are more aggressive than others (CU Boulder), etc. But you have to look at total price because - as an example, a Florida State (not on your list) will be cheaper full price than CU Boulder after merit. Just using that as an example - but some schools (WUE) will have a lower sticker price than others after merit.
As for smaller schools, I think all in Washington offer merit, all in Oregon except Reed, and in CA, outside of the top Claremont schools (Stanford, Cal Tech, some of the Claremont Schools (I know Pitzer has small merit…but that might be it) won’t offer merit - but the rest will at least have the possibility.
