Since you plan to polish it at least once, follow that with a sealant. A sealant is more durable than wax and can last up to a year or more. It's one more (strong) layer of protection between your clear coat and all the environmental cooties floating around. Plus, with most sealants you can still apply glaze and/or wax over it, so if you do get any light swirls afterward you can still hide them with glaze/wax until the next polishing session. Some sealants are difficult to apply correctly, but a popular one with novices is BlackFire Wet Diamond for its ease of use.

Adding to that, even if you decide never to polish again, you can still use your PC to apply wax. On large areas like the hood and doors it makes the job much quicker. It can also be used for sanding wood if you use pads that are meant for it, but that's a different forum entirely!
