I can't say that I have made the transition but if I had a new CNC and were going to get into making cabinets, I would purchase Mozaik software and learn to use it and setup to make some test cabinets. This can help you with material amounts and building the cabinets gives you an idea of time.
As far as cabinets go, I would look into an edgebander and nothing else. Buy all of your doors, drawer boxes, molding, and anything you can outsource. There are plenty of companies that specialize in these products and can make them a lot more efficiently than you can in your shop. This allows you to do other things that make you money like cutting and building boxes and having time to take on more projects. Even if it cost you the same to make a door as it does to buy it then you are breaking even. If you took that time and did something else that made you money then you come out ahead. Also use all prefinished plywood, this will save you huge amounts of finish labor.
Pricing you have to figure out on your own based on your time and overhead. Some people price by materials and labor, we price boxes by the foot and then add doors, drawers, and any extras.
