An easy solution - open the package when the delivery person comes or when you pick it up from the delivery office. The delivery person can take a photo and act as a witness. If you take the package from the local delivery office, there are cameras and staff, so I can't just swap a ripe apple for a rotten one.
Where I live we don't have the habit of just putting the delivery on the porch for a few reasons. First, it's ridiculous if you think about it - no one signed for it, so how could you mark it as delivered? I don't get the US in that regard. Secondly, most of the houses have fences, so the delivery person can't come to the house even if they wanted to. You're basically required to meet the delivery person.

That would massively slow down delivery times, especially if the packaging is non-trivial to open/inspect. Not to mention that not everyone works a comfy remote job where they're at the door the entire day.
I'm at home most of the time, yet I prefer to go to the delivery office to pick up my packages. It's a 5 minute walk, as they're all over the city. Might not work well for big car-first American cities, though. I prefer going to the delivery office because I hate waiting for a delivery person to show up and wondering if I have time to go to the bathroom or not.
But I agree that not everything is easy to inspect. Most things seem to be, though. Another issue is not wanting third parties from seeing what you've purchased.
