Building on @tamagotchi’s great insights above … @eyemgh doesn’t post as much here these days, but you can look through old posts from him to see that he knew a lot about Mechanical Engineering at west coast schools and thinks incredibly highly of Oregon State. His son went to Cal Poly SLO and loved it, but I have the feeling that @eyemgh would put Oregon State at the top of the list of admits you have above (though obviously I can’t speak for him!).
Congrats to your kid on WUE as well! That’s really excellent. Great job!
