Mark:
When we did kitchen remodels, we left the cables hanging out with about 3 feet of slack. When the cabinets were being placed, all that we asked for was a reasonable hole to permit the cables to pass. We would come in and wire up the old-work boxes (always metal), install the devices and leave the boxes hanging there. The cabinet people would then know exactly what needed to be mounted and the box dimensions (the finished box was right there in front of them). With about two feet of slack in the cable(s), it seemed to be easy enough for the cabinet guys to get the cutout right and in the correct location. They would just screw the boxes to the cabinet through the box ears and install the plates that we left them. This strategy generally worked well.
The over-sized holes stem from the large use of plastic old-work boxes that are assumed by the cabinet guys as being the norm. Using metal boxes, you gain about an extra 1/8" all the way around. It doesn't sound like much, but when it comes to plate coverage, it can make a huge difference.
Now bear in mind, we worked with more upscale kitchen remodeling companies that were willing to pay a little more to get it done right.
