This "family cars must be huge" take is a weird take, too. Can a Ford Focus fit a car seat? Yes! Then it's big enough for a couple with a child. I guess I'll add rear doors; even if a car seat would fit in the rear of a coupe, I wouldn't recommend that for anyone.
If your family requires more than 4 seats on a regular basis, sure, get a minivan; but I don't understand the appeal of an F150 or other large vehicle as a "family commuter" for, we'll say, the family of median size.
Two children fit in the back of the Focus until we got rid of it. They were 6 and 9. By that point it got leas squishy because the car seats get smaller with age.
Littlest kid went behind the driver because it was stick.
