I have a GMC Acadia with the 2 rear captain’s chairs plus the fold-flat rear bench seat, for a total max capacity of 7 or probably more realistically 6.
Like you, I didn’t want to have to upsize any further. Luggage space is somewhat limited with the rear seat up, but so far that hasn’t been a problem because of storage space between the 2 captain’s chairs in the back.
Just another option to consider.
With children, the problem is that with the absolutely massive car seats these days, a baby in a car seat takes up as much space as an adult. So a vehicle may, in theory, seat 3 across a bench, but if one or more of those is in a baby in a car seat, the situation isn’t workable.

Not sure if this was true or if it was changed in later models. The 2012 Traverse/Acadia/Enclave the 3rd row seats were not rated for child safety seats. Was told this by someone who traded theirs off for Toyota minivan. He hated the thought of getting the van but had 3 kids 4 years and younger.
