Congrats on the new car!!!!
It might be smart to not use a car wash, at least that's the consensus here in this forum! Regular car washing with ONR or regular car soap (never dish detergent) is a good idea. In fact, since you mention ONR, it's on sale with our forum sponsor
DetailedImage for a few more days. $10 off of a gallon, $5 off of a quart. Supposedly Optimum is coming out with a new formula, but people have used this formula for quite a while with good results, so why not take advantage??
There is no need, protection wise, for waxing every time. It never hurts, but even a high carnauba wax will last 3-4 weeks, so the other times would be for appearance. Your best bet is to get a sealant that will last longer, and then if you choose, put wax on top of that for looks. Zaino is popular, Chemical Guys is popular, and I'm very tempted by Blackfire for a dark colored car (but I haven't bought it because I have plenty of sealant left still).
If you decide to wax frequently, you may want to consider Optimum (the same people who make ONR)
Spray Wax. I have no experience, but people recommended it to me in a thread below - I decided to just not worry about waxing that frequently. My personal favorite is
Poorboys Natty Blue. I even like it more than CG 50/50, and it's cheap at $20 a can.
