Hmart has pot stickers that work wonderfully in the Air fryer. House of mandu even gives AF instructions. 360 at 12 min turning half way. I do spray mine with a little oil. Bibigo's brand also works well. I also like the Pulmuone brand. Over at Target Chung's puts out an eggroll that tastes great air fried. No extra oil needed.
I am only cooking for one and have a 6.8 qt and still wish it was an inch bigger in diameter than 9 inches. You only want small batches of food in it, preferably in 1 layer. If it's over stuffed it won't cook evenly.
I had a dial air fryer initially. It's not a big learning curve to transition to cooking function buttons.
