Any thoughts on sumo springs to minimize sag? Also, tell me more about WDS with smaller unibody vehicles. For instance, wife has a 2020 sorento and that is a no go per Kia. 2016 was ok BUT that had an additional mounting point for a bolt on the hitch receiver.

A receiver must have AT LEAST a 4 decently space bolts to support a weight distributing hitch. Some of the receivers for SUV's on etrailer are rated for WDH; others are not. Make sure the receiver you buy has adequate spacing between the mount bolts, is made for your model Sportage, and is rated for at least as much weight as your Sportage maximum is.
I use an E2 600/6000 on my Hyundai minivan (re-badged Kia Sedona). There is a smaller model E2 450/4500 that would probably serve you well. Just like your Sportage, the Sedona had a much higher tow rating outside of North America - even though it's the same vehicle in Australia and Europe. So I wasn't worried about body strength. And 135,000 miles since installing the receiver (238,000 total miles) and towing our A-frames and U-Haul trailers, there are no signs of unibody distortion.
The E2 WDH - properly adjusted - lifts the rear end of my soft suspension minivan so it doesn't squat so bad and transfers weight back to the front drive wheels so the vehicle handles pretty close to stock. It's done the trick at preventing receiver ground strikes at road dips and humps. Also, no sway up to 80mph.
Previously I towed a pop-up (Coleman 10ft box) with a 1993 Ford Explorer - no WDH. That was a miserable experience that started swaying at 62mph, and had the nose of the Explorer pointed at the sky. I could not believe the difference the WDH made when towing. DW is willing to drive towing with the A-frame, WDH, trailer brakes, and minivan - it's that close to stock. She hated to even ride in the Explorer because of the steering issues and sway.
I can't tell you about Sumos or air bags on the rear - last time I towed with air bags on the rear was 40 years ago with a 1980 Ford LTD station wagon towing a 2 axle boat trailer and sail boat. I do know that the air bags don't transfer weight to the forward wheels the way a WDH does.
hope this helps
