Would a rational person ever choose marry a person they didn't prefer? One could argue the "business" relationship or marriage of convenience, but these are more the exception than the rule.
Would those still not be marriages of preference? Preference can, and often does, involve a whole lot more than mere sexual attraction. So, fwiw, I see no reason for this distinction.
Okay. Then that just removes that distinction. The question remains: would a rational person her choose to marry a person they didn't prefer?
