I am mostly thinking about what you see in aerosol cans at Walmart, Home Depot, etc.
Are they pretty much all pyrethroids or are there significant differences iin their ingredients and formulations?

For most of those (pyrethroid family) it will be differences in application and mode of transport. Hornet spray may shoot in a long (10-15ft) stream and foam on contact so it sticks to the nest and you don’t get stung. Room foggers are the opposite they spray in a fine mist that hangs in the air and settles slowly on all surfaces. Ant and roach sprays (perimeter sprays) have formulations that don’t quickly degrade (making them unsuitable for broad application) and may contain additives to adhere to surfaces and/or the bugs as they walk through. Powders are sometimes used under appliances and cabinets that last a long time and coat any bug that walks through it.
It’s the same really with any pesticide family. After mode of action (pesticide chemical) the important thing is getting it where you want it and keeping it away from where you don’t.
