All one piece rotors I know of are SS, although you can buy CF

I wouldn't have guessed that slightly thicker rotors would be
appreciably better at "shedding heat".

Agreed. Initial temperature rise might be slightly less rapid due to the
larger mass. Once steady state was reached, as on a long descent, I
doubt it would make any difference at all. Surface area is what matters
then, and the difference in surface area would be negligible.
