Even with back-seats being used, bring back the station-wagon:
The 90s Buick Estate (a behemoth of a wagon) was 9 inches shorter than the Kia Telluride (one of the smaller 3-row vehicles in the US) and seated 8 (though it would be 7 today because front-row bench seats appear to be disallowed except in pickups).
The Estate's contemporary Ford Taurus Wagon could also seat 7 (though two adults in the 3rd row is not comfortable, it worked for short drives in a pinch) was almost 20 inches!! shorter than a Suburban/Escalade.
