You're conflating the magnitudes. You can't directly compare the number of multiplications with the number of transistor switches or CPU cycles required for a single multiplication.
Also, the number n has O(log(n)) digits.
The number n has O(log(n)) digits, but that has nothing to do with the subject at hand. The nth fibonacci number has O(n) digits.
