With just you alone and a few items inside the truck and in the bed either will work for you. With just you I would add 1000lbs to the dry weight. So for the bigger trailer that puts you at 9300lbs with a loaded tongue weight of 1150 lbs. with a WD hitch you will be at max GVWR but under the axle weights. The Power Wagon can handle being maxed out.
And yes, the Power wagon is the best factory made off-roader available next to a Wranglet Rubicon. The Ford Raptor is more for dune running where the Power Wagon is more for crawling.
I think you will be just fine.
