Just be careful what kind of screws you use. I built my kitchen cabinets about 25 years ago and hung them with French cleats.
Lots of heavy plates in one cabinet.
All was fine until one cabinet spontaneously fell while I was having morning coffee. After examination the screws I used ( drywall type screws) had sheared clean off. Magically, the cabinet and counter were fine and only a few plates broke.
Needless to say I found some larger diameter screws that weren’t hardened like drywall screws and made for the task. I think they were Strongtie timber screws.
I live in earthquake country so I did add a couple of lower screws to stop the cabinets from jumping off the cleats in a bad tremor. That might save the cabinets but probably not the plates.
