U chips are just P chips with a tighter power limit, they’re not inherently “more efficient” (same architecture), just a lower cap.

is there really anything stopping you from setting a lower cTDP if that’s really what you want?

Where would you set that? The only PC I’ve seen that lets you explicitly set a target TDP is the Steam Deck, the most I’ve seen elsewhere is the ability to turn off turboboost and limit clock speed.

Regardless, a default TDP above that of a U chip in a Nano is still an odd choice given that machine’s lack of cooling and battery capacity resulting from its size. It means that a lot of buyers who have no idea how to reduce it are going to have a subpar experience.
