4. Touchscreens - I'd say these are useful for running android auto or apple car play? - But this would fall into your tracking/internet criteria for Google at least.
I'm curious your objection to a touchscreen when it sounds like you are just using a phone with bluetooth? Wouldn't a phone with a touchscreen represent the same tracking + safety hazard?
I used to have a 15 Rav4. There was a shitty touchscreen but if you were just trying to interact with it minimally and just wanted to be able to pause music or skip a song, there was physical buttons on the steering wheel so you'd never have to touch/look at a screen. It fits all your other criteria too, except the mpg.
There are important differences between these two touchscreens, though. One being that I use one of those windshield suction mounts so that it's in the line of view of the road much more so then below the center console. The other being that my fingers can tactilely guide themselves using the edges of the case with very little concentration on my part due to my much more frequent usage of the phone than to the head unit.
And CarPlay won't even necessarily work as a reliable aux. I've been in plenty of rental cars where somehow my music lags or stutters over it. It's trash.
