I agree that it's one of those shots with multiple options and no clear cut cropping solution. The focus was the delivery guy, but other elements were also interesting - particularly the bricks...
My experience with cropping is that it's obvious or it's the whole frame, or move on to the next photo. In the middle there are the times where compromise takes hold and not always toward a positive result.
Sticking to the original proportion is a real limitation. The only crop that I have not used with any frequency is narrow portrait - it seems unnatural... so maybe I should work with that format
.
I think that your ability to shoot from the hip will improve over time as you do more of it. With the digital you can at least see the results immediately. I did one session shooting from a park bench using an ND filter to catch movement of people walking past. About one or two shots from that session were usable. Placing the camera on the bench at least gave a reasonably level shot.
Cropping and choice of cropping is one of the topics that is enjoyable to revisit many times.
