aside from the twice mentioned divine command, is there any other benefit to the procedure?
Typically, the things that get brought up in that context are cleanliness and the lowered risk of diseases caused by lack of said cleanliness.
Personally, I think this is a pretty ridiculous argument in the modern world of running water and widely available showers. Even if you are hung like a horse, it just isn't that big of an area to clean. Circumcision typically exists in cultures that come from hot and dry areas, like Middle East and Africa, where this may have been and maybe still is a problem.
In the Western world and US especially circumcision was popularized as a means of preventing masturbation back when masturbation was thought to be a terrible disease. Didn't work very well for that, but it did become widespread, parental logic being mostly "because everybody does it" and "I had it, and you will too". IMO, neither one is a very good reason for inflicting anything on your child.
