Unfortunately I cannot share any data from the accounts I manage (mainly competitors are the shady ones), but simply you can go let's say instagram or facebook, and log the ads you saw (without clicking) in a single session (like first 20), then you can go check them. Probably what you will be interested will be almost at the end of the list, the first ones will be high margin products. To be honest, I don't see hope for ethical small business without user tracking. That's why Facebook is pushing that angle, even it is very small percentage on the overall. Big players will be almost not effected anyway.
