SQ8 hand wash vs touches vs touch

I know I know, it's been discussed. I'm only planning on keeping the car for 4 years. By the time it's paid off and warranty falls off, my kiddo will be old enough for front facing seats so going to go to an rs6 or another rs3.

That being said, there are already swirl marks, a few very MINOR scratches. No ppf or ceramic.

Would you hand wash(newborn, so little time), touchlessnor go through a touch? None of my touches in the area have memberships.
