Lots of reasons to like a 4x4... It's just not as necessary as some would think.
Full disclosure, I've owned mostly trucks since 1974, and more have been 4x than not, yet I have plenty of reasons to not own one, all terrain/climate or job dependent. Resale is better, I agree.
Parts complexity, increased service requirements and a bit lower mpg's (and payload) are the cons. Anyone who doesn't think that they are more costly to own obviously never had or heard of codes being thrown saying "service 4x4 system" that end up costing the owner $1-2K.
My 2015 F150 (I only owned it a year and a half) never saw the front end engaged. Never. The current 2019 Ram 1500 is now 21 months old, same thing. All depends on what the truck is primarily used for.
One other advantage for the 4x2 is not having such a tall truck that you have to use a step assist to get up into the bed... Long gone are the days of reaching over the side to get something unless you are like 6'4".
I still think that the GM G80 rear diff (it's an Eaton, right?) is the type of mechanical locker that all three domestic brands should have. Nice and simple, no unrealistically low engagement speed limits, no electronics to futz up.
The YT vid below is actually a 4x RAM yet he shows at the 2:00 mark why having a rear locker would have likely gotten the truck out:
