Orijen is probably the best kibble out there. Merrick Grain Free is all good and a little less expensive.
Grandma Lucy’s Pureformane line is a great freeze dried line.
My girl inhales her food too. When I give her commercial frozen raw, I only give her 1/3 of her meal at a time spread out as thin as I can get it on a small plate so she has to work for it a little. For kibble, I use a portion pacer ball in her bowl. Basically a big ball in her food so she can’t gulp it down too fast. Dog Games has an interactive feeder bowl shaped like a 3D flower with a bunch of nooks and crannies so she has to eat her food a lot slower. Sometimes I will put 1/2 her meal at a time in her Kong Wobbler toy. She loves it and makes her eat slower.
