I feel most comfortable with the pilot wave approach in this regard; it is generally compatible with emergence-from-causality type theories.

Free will in the fundamental physics sense is most likely an illusion, probably one that confers mental hardiness in face of adversity out of one’s control.

However, it could be an emergent phenomenon and thus irreducible to individual quanta anyway: more than a sum of its parts. Fundamental interactions do demonstrably yield complex structures itself capable of higher order interactions.
