Sounds like an Instacart order that went to the wrong house. If I was the person who had made the order, I would receive a picture of my groceries, delivered. When I saw that my groceries were not on my doorstep but on some other mysterious doorstep, I would immediately contact Instacart customer service. They would apologize and refund my money. They might offer to have a different shopper get the items (new ones from the store, not the ones on your doorstep) and deliver them to the correct address.
The Instacart shopper might get in trouble, but the shopper might also have a reason for delivering to the wrong house--maybe the customer gave the wrong address, or maybe there are two North Streets (or whatever) in your town. In any case, the shopper would get a warning from Instacart but would not be charged for the groceries.
In addition to Instacart, there are other services that might have done a similar grocery order--Uber Eats does this now, and some stores use their own people. So you could call Instacart and explain, but they probably would not be able to track a wrong delivery and even if they could, they would tell you to keep it or donate it or whatever you like.
In any case, you get to enjoy the strawberries etc. No one will be coming to your door looking for it. I once got an enormous papaya in my Instacart order, and Instacart was like "Please enjoy your free papaya!"
