I've used a varity of lures from hawbakers or dobbins. There are a bunch of good items but as far as grocery store items, ive used marshmellows, eggs, sardines, cat food, dead birds, pretty much anything. But I mostly use coilsprings and long springs so haven't done much cage trapping.
Also a half ear of corn works great or even grain for cattle. If you live on a farm. We always had problems with coons getting into cattle feeds same with dog food/cat foot.
