Paint Care Concerns

My wife and I purchased a new car (2018 with 90 miles) two weeks ago. Soon after we received a care package from a friend which was a tote with various car detailing goodies to keep the car looking and feeling like new. Included in the tote was Nu Finish liquid car polish, CarGuys hybrid wax sealant, and Chemical Guys light duty clay bar & synthetic clay lubricant. My plan is to give the car a full service wash & dry followed by through clay bar & spray treatment. After the clay has pulled off the contamination, I will need to wax and polish. If anyone is familiar with these products, please chime in with any suggestions or comments. Would it be best to apply the polish before the wax? Wax before polish? Will multiple coats make a difference? What would you do?
