All good stuff from experience. Couple things on the RV pad, I'm not sure if you plan to actually use it for an RV but if you do I recommend:
1. Having 20 amp service to power the AC especially if you plan to use it for guests. It is still handy for a boat (i.e. heater).
2. Having a sewer pipe stubbed out as it is much easier to dump waste when you get home from a boating trip then to sit in line at a dump station and then fork out bucks. I found my cleanout pipe last year and what a time saver.

For communications, run smurf tubing and just use a mud plate in each room. You will have enough room to run a bunch of any low voltage stuff. Who knows, everything is getting more wireless all the time.

I'm remodeling my kitchen and found out to stay away from induction cooktops unless you have the top of line ferrous cookware. My magnet didn't recognize any of my pots and pans and the cooktops heat the pans not the cooking surface. I am going to a gas cooktop because my fine, fine cookware would probably scratch a ceramic top over time.

Also, get your refrigerator opening big and deep enough to handle the bigger refrigerator. I had to go with a countertop depth model since the opening is next to the dining room entrance and would stick out and in the way.

Enjoy watching the home getting built and check often to see how things are getting built and for design issues that you may want changed which are cheaper at that time to change then to realize it later.
