Yes, a compressor big enough to fill fires after airing down for wheeling needs a battery connection. the 12v accessory plug really isn't enough juice to do that in a reasonable amount of time.

On the website, it says flat to full in 4 minutes. Basically I've only ever used it to top off, but I would assume if you're airing down and then want to get back up again, maybe 30 seconds to a minute per tire or so. Pretty handy tool, especially if you have a bunch of other Ryobi stuff.

I will do the same as I did on my Runner, supply power to a SAE plug both in the grill and at the trailer plug harness for my auto cut-off compressor. Wire one of the Aux switches to a 30amp relay to power the runs, that way I don't need 20' of air hose, just the 10' coil that came with the comp.
Most pancake compressors are 110V, and the built in 150 watt inverter is not nearly enough, so you will need a 300 watt inverter to run it unless you can find a 12vdc one.
Your best bet is not to use one that has a tank. That keeps the size down and will run while you're airing up. Look at ARB or Viair for options.

Beats walking.
Yep, pretty much. FWIW, you can run a tank on the compressors from ARB and Viair if you wanted to, say run air tools off them. But they don't require that just to fill tires.

Most common place is under hood, and most vehicle specific mount kits will come with a heat shield of some kind. The off-road specific ones like ARB are built to handle high heat, but all the same, heat and dust/road grime are something to consider when mounting in the engine bay.
I’ve seen guys mount them wherever they have free space in the back as well, just keep in mind you’ll have longer runs to get to your battery which will most likely be harder to get to in the event there’s a problem. Pros and cons to everything

Viair has a bunch of different models and they rate them based on tire size so it's pretty easy to comparison shop on https://www.viaircorp.com/compressors
I ran the Viair 400H (hard mount version of the one linked above) in my Xterra for years without a hiccup. Filled my 34" tires and a friends 33" tires in one go.
I have a Viair Onboard Air kit with the 400c compressor and 2.5gal tank. Will have to figure out where to mount the compressor and tank, should be entertaining. Tank can go underneath the truck somewhere mounted to the frame, compressor needs some place relatively dry and clean.
