Since I elected not to have either done on my engine, I can't comment on their value. Perhaps if I had the rotors ceramic coated the coolant temps would be higher and oil temps lower but, my oil temp was at 160-180F and my coolant temps were at 200-210F, so I don't think ceramic coating would have done me much good. My understanding is that it shields the rotors more than any other component from the heat of combustion - so would probably help keep oil temps cooler. If you are going to wind your engine past 8000 rpm then dynamic balancing might have merit - otherwise my experience with 3 rotary engines is if you use the correct counter weights for the weight of the rotors you are using - you don't need to have it dynamically balanced. On the other hand, if you have the time and money - why not?
