touchless is not recommended...they use very harsh chemicals in order to get the dirt off...will strip your wax/coating/sealant and clear coat over time...
best is to do hand wash with quality products yourself, and proper technique. This video is a good intro
I prefer hand wash when I have the time, detailing is my meditation. If I don't have the time though, rather than let it go dirty I'll go for a touchless wash without any worry. I just make sure to ALWAYS wax by hand immediately afterward.
MRCW- what product do you use for cleaning with your foam cannon?
chemical guys snow foam wash...
you can buy the whole kit for $100... need a modest pressure washer... or you can get foam kit that uses a garden hose...I have both because sometimes it's a hassle to get the PW out... if im doing a couple of my vehicles at once over a weekend, then I use the cannon with a PW. otherwise I use the garden hose kit...I foam one side, let it sit a bit while I wash wheels then switch sides...
I have an air compressor based foam gun that works just OK, and only hand wash cars. I rather leave the car filthy than wash the car in a harmful way. All premium brands soaps work fine; just keep the concentration per the directions on the soap. Grit guard is a must along with dedicated wheel brushes and mitts.

like others said... still use 2 bucket method with grit guards in each
For heavier cleaning I use Ammo NYC Frothe, it's great stuff and I know it works because I saw him use it on a rare Bizzarrini that hadn't been washed in 30 years. It works well and is mild. https://www.ammonyc.com/shop/ammo-frothe-hoseless-lift/

I gave up on the 2 bucket method, but have separate mitts for wheels and body. I did not think the difference between 2 bucket method was worth the extra time. I did not notice more swirls after a quarter year of doing that exclusively vs. what I was doing previously. The extra time was at least 15 minutes extra per car. Add that up over year for me and that's 15 hours extra needed to use the 2 bucket method.
