Having owned a stock '07 FJ…
Having owned a stock '07 FJ with locking diffs and upgraded off-roadish tires, and owning several older true off-road SUVs and trucks (pointing that out as many modern day SUVs and trucks are definitely tarmac queens), in addition to owning an Outback XT (with mods similar to a Wilderness edition, including Geos) and an Impreza with mods similar to a Crosstrek and a WRX, I have a decent amount of off-tarmac experience. While, from an engineering standpoint, there is a difference between 4WD and AWD, it does not mean one is automaticly more capable than the other...especially in modern days. As another poster stated, they have a 4x4 that will get stuck easily. If the 4x4 doesn't have limited or locking diffs (front, back, center) and/or electronic control, the vehicle can easily get stuck in uneven and/or loose conditions. Suspension has a huge impact on agility and traction, again a 4x4 with stock suspension, especially modern ones tuned for the tarmac, is more likely to have issues. Clearance...clearance is clearance, whether RWD, FWD, AWD, or 4WD. I am just as confident in my Outback and the FJ and several of my older true off-road SUVs in most situations.
We did talk to a NPS ranger that manages a National Monument out west (we lived in Utah for the last 3 years until we moved back to the Midwest) about "road" conditions in a National Monument that is entirely 4WD High Clearance. He was aware we were using our Outback, didn't make a peep about it. He did advise a few routes to avoid, with any vehicle, complained about have a few weeks of recovering vehicles, both 4WD and FWD and a few AWD (he specifically mentioned Toyota RAV4 and Honda CR-V), and mentioned it's really expensive to recover a vehicle.
We enjoyed our time there, that included a nice section of steps, that we navigated easily to the dismay of a group of Jeep/Toyota/GMC trucks that had some difficulty. We ended the trip in a section with deep dips, so we had to use engineering to overcome those obstacles without damaging our front and rear numbers...did I mention, we saw a 4x4 with a rear bumper pushed up after passing through the same section? 😂 And it had way more clearance than we did.
