I have never seen any pilot with french cuffs, ever. Airline uniforms are not designed to be fashionable and snazzy (which is a completely different argument). Would you really wear french cuffs with shirts that have shirt pockets, skinny uniform ties, and uniform style pants? I hope not. Have you ever seen a police officer or security guard with french cuffs? That seems like something you might see on Reno 911, along with the guy with the short girl shorts.

Plus, if you have french cuffs with cuff links, you would have to take them off every time you go through security. That alone is a no brainer.
