IMHO, many of the mid sized SUVs make a fine choice. On some, the third row is cramped, so test that out first. Honda Pilot, Toyota Highlander, and Kia Telluride come to mind. The Telluride gets high marks for 3rd row room.
On the Volvo, I am not a fan. Consumer Reports, who some trust, some don't, rates it poorly: "The 2021 XC90 ranked as the least reliable brand-new Volvo in Consumer Reports' list. According to Consumer Reports, the most troubled spots are the drive system, suspension, brakes
, body integrity, and power equipment. The result is that XC90 problems have been reported across a variety of crucial components." New, the Volvo has a premium price over the Toyota. Honda or Kia. Used I would think much of that evaporates.
Myself, given a choice between a mid sized V6 and a small turbo'd 4, I am picking the V6. Telluride has a nice trailer package option, that includes 7 pin wiring. You have to look hard to find a Telluride that is not marked up over MSRP, but they are out there (just may not be your local dealer). Until supply improves, used Tellurides are very close or higher than brand new!
