I have a 2016 pathfinder and with the third row up you can still fit a couple suitcases. You may have to have them upright, and there isn’t much room (with the third row up) but I don’t think there is any less room than the cargo area of a minivan (we have never owned one but have rented them on vacation).
One other thing you can do to seat 6 is just bring one side of the third row up (2 people up front, 3 middle, 1 back). In my model anyway. We’ve done that when going to the beach. But the person in the third row would have luggage beside them.
