You didn’t mention height and isn’t that the actual issue?
Increased hood height kills people and creates an absurdly large blind area. Massive pillars add roll safety but create horrible blind spots in left hand turns.
A sedan is the perfect shaped car in my opinion. Wagons are nice too.
And nevermind that often these cars come with other compromises that signal they aren't really intended for "utility" use, for example the Taycan can't fit a regular tow receiver so forget about using a bike carrier with it other than the overpriced two-bike one that is available from the manufacturer.

It seems people buying new cars mostly want big cars.
Are you sure about that? In North America, other than the Crown Vic in its heyday, Ford also had the Escort, the Festiva, the Tempo and the Taurus for sedans, all of which were smaller than the Crown Vic, which was the largest car they sold.
Per wiki, Crown Vic sales peaked at 114k in 1999. In the same year, the Taurus sold 368k and the Escort sold 260k. (The Tempo was discontinued by then, but was typically moving 200k+ per year.)
More to the point - at least for automatic transmission variants in the early 90s - even the base F150 could certainly out-tow Crown Vics of the time, unless the latter had a tow package, which would push the rating up to 5000 lbs (..same as the lower end F150). Later on the delta was a lot greater (in the truck's favor) as the tow packages for the cars were phased out.
Nowadays the minimum ratings of F150s (even with shorter beds) is 5000lbs, or more. The smaller CUV/SUV platforms are usually rated ~1500lbs *max*, with some of the larger truck-based models obviously running in the same range as the trucks.
TL;DR - Even back in the day the "typical" sedan was still only rated for towing small loads, unless specially ordered with towing packages. Now..all that said, the frequency with which typical F150 owners ever actually tow anything is a whole other question.
