Is free will actually a spectrum?

I can think of the following three stages of freedom of will.
1) A determinitard blindly following orders. E.g. someone says "Get vaccinated!" and he does it immediately.
2) Someone presented with a finite number of choices freely decides based on his personal preferences. E.g. when asked "Sex with a man or a transwoman" I chose the latter since I'm not gay.
3) A full free will Chad acting on his own without being prompted externally. E.g. me freely coming up with the idea to make this thread.

How can we further formalize this to solve the question of free will scientifically once and for all?

As I understand it human males are attracted to features like wide hips and narrow waists is because it indicates the woman can get pregnant but currently isn't, but in most species enlarged breasts are a temporary sign that a female is pregnant or breastfeeding, meaning she is already occupied with a child and isn't available to make another - so where did this attraction come from?
