I'd totally agree with that part of your recommendation. After washing, it's easy to closely examine and feel the paint surface with your hands.
Since we're talking about a new(er) vehicle...people should know that despite that (and a good wash)...they are not exempt from having pollutants and other foreign substances (tree sap, road film, etc.) on their exterior paint and even wheel rims or glass.
Clay-barring did not cause any negative surface affect on my new vehicle. None whatsoever. It was properly done with a lubricant as instructed with clay bar products. That eliminates any real risk or problems when following directions.
Any fear thoughts of doing it are unjustified, as it's a common 2nd step (after washing) detailing step done routinely by professionals on expensive 6-figure cars all the time, and when done correctly with a common lubricant...there is no risk whatsoever. You can even clay-bar your windshield and other auto glass surfaces.
Nonetheless, where the ultimate goal is to get to a well-protected paint surface like stated by the original poster...polishing, sealing, glazing, and waxing are all options once a clean surface is established after doing a clay-bar treatment.
Here are 2 good summary articles on the process, the materials, the purpose, and the results:
