2015 buying advice, what to look for?

Also be aware that with a 2015 you are missing some features the later trucks have. Like wireless charging, CarPlay, and adaptive cruise. Maybe some more?

If I knew what I do now I would have gotten a later model year than the 2015 I have. I added the wireless charging but the CarPlay and adaptive cruise aren’t cheap/easy to add. Just FYI.

I don't know - Sometimes simplier is easier to maintain and cheaper to service.

Stay with the 2018-2020 6.2 with the 10-speed.

My 2015 Denali does speed up and slow down so did they really make 3 different levels of cruise control in 2015? I would also argue that most of the time while I don't mind the adaptive cruise it is absolutely brutal about minor things causing it to absolutely demolish your momentum if you are having to occasionally maneuver around a slower vehicle. I personally would prefer normal cruise after having it for half a year but it isn't as bad as I thought it would be.

My understanding is the 2015 wireless charging center console lid is also outdated and won't work with most modern phones. I also can say that my Samsung Galaxy S23 Ultra doesn't even lay flat in the center console charging area so if you have a good size phone it is moot anyway.

Not sure about yours but I can turn adaptive cruise off on my Sierra.

You can update your charge module and phone size from a 2018-2020.
