It's a practical necessity for the cooling systems.
An engine is *most* thermally efficient when there is the greatest disparity between temps on the intake air charge and the exhaust gas temperature. Without going into a lot of inside-baseball type equations involving thermodynamics and mechanical engineering that literally 99.4% of you won't understand, just think of it as "a hotter engine is an efficient engine".
But when you design an engine to run hotter, you have to have a cooling system capable of keeping it from cooking itself. And you need airflow - lots of airflow- to help with that cooling. That means a bigger grill for more airflow.
Also, when you factor in full size SUVs like the Tahoe/Suburban , which are designed to tow boat, RV or horse trailers, there are cooling systems for the transmission too, not just the engine. Plus, the air conditioner also has its own radiator. On some turbo models of smaller SUV's (Toyota/Lexus/Honda/Acura/Hyundai) the intercooler has its own radiator too.
So there could be up to three different "radiators" (cooling systems) in the grill, each needing "x" amount of cubic feet of airflow per minute, in order to work properly.
That's why you need giant grills on cars now.
Previous engines, of course, didn't need lots of air flow.
Either that, or it's car fashion.

Just recognize you hypocrisy should you ever complain about the weather, flight delays/cancellations or a horribly bouncy flight.
What hypocrisy? So my Suburban now creates air turbulence? Besides, I have a Suburban; why would I fly?
Your Suburban is also far more fuel efficient per pound/passengers than a jet, too.
Maybe if the PP has 9 people in it.
But when the PP is driving around in it alone? Nope, the Suburban is even worse than flying.
As a pilot, I laugh at your utter ignorance.
Whatever entertains you, I guess?

Wouldn’t a minivan make the most sense?
In my case, it is cargo capacity and towing capability. I do also have a minivan, but it is lacking in both these categories.

"Makes sense" would be a minivan.
This would be "wants an expensive behemoth."

Precisely why I would never buy one.
So I guess you'll also never own a Tesla, most Toyotas and Subarus, most Hondas, Hyundais and Kias, about 1/3 of the BMW and MB offerings, either huh?
Personally, I think limiting yourself in such a way is a dumbass move, but you do you.
Do you really want to support Communist slave labor?

Yeah, I'm stuck on that too. They look largely the same, but somehow even boxier. Ooh la la!

What focus group keeps telling the automakers that they like these larger and larger grilles? The entire Lexus fleet has been ruined by the giant grille trend.

The dash is nice but the outside is a big box.
