There are the differences in the Extended Diversion Time Operations (aka ETOPS) that I referenced in the original post and the crew duty that Markerinbound noted, and I wouldn't be surprised if there are others.
Further, regulatory oversight - not just of operations, but of aircraft modifications (i.e. Supplemental Type Certificate changes) is more relaxed in the freighter world. Just one example - back in the 1990s UPS re-engined some 727 freighters with Rolls Tay engines via an STC. They had an incident where all three Tay engines flamed out at the same time (they managed to get them restarted and landed safely). Although the FAA initially came to Boeing, turns out Boeing had no involvement and had never even been contacted about the STC - it was a purely DER project. That would never have been allowed for a passenger aircraft.
