The first two options kind of go hand-in-hand. A lot of the people who were offended by Trump's attacks against the McCains happened to be college-educated suburbanites.
Agreed. It's laughable to say that Hispanics delivered the state to Biden when they actually shifted hard rightward across the board, including in AZ, in 2020. If anything they actually made the margin a lot narrower than it would have been had they voted as blue as they did in 2016. Case in point: the very Hispanic Santa Cruz county swung more than 10 points to the right from 2016. As for the other options, I don't think Jeff Flake was that popular in AZ, and those angered by Trump's criticisms of him were probably on the fence or tilt Biden anyway. Voted for option 1 in the poll since as you said option 2 is basically a part of option 1.
