Based on frequency of usage: Butter and olive oil are tied for first place. Then lard and bacon grease. Occasional uses of other oils, corn (always when cooking corn), canola, walnut, soy, etc. Then rendered duck fat. Then everything else except margarine. Modern margarine doesn’t have that weird taste it had when I was a kid, but I can still tell if I get served margarine.
Unsalted butter for baking, salted for toast or baked potatoes.
