They get better gas milage than any truck or truck based SUV.

Their aero isn't as good as a car but it's better than a truck based SUV.

Fold the seats and you've got a trunk only slightly smaller than a minivan without the 3rd row.

AWD SUVs are readily available and generally the standard. FWD is generally reserved for people who want to go out of their way to be economical about it.

Trailer hitch is solved with $300 and a trip to Uhaul (or for the mechanically inclined: $120, Amazon and a 30% chance of needing a drill). With modern horsepower and brakes you can comfortably tow some stupidly large stuff with crossovers so long as you've got a weight distribution hitch to take some of the weight off the rear axle.

Crossovers do nothing great but they do everything passably well, just like the station wagons of the 1950s-80s they replaced.
