I think you're taking the wrong message away from the following simple idea: "Good decisions depend on taking the available information into account." If we take this for granted, then it's not clear why free will is a good thing.

How would you say pre-determined actions and free will are compatible? I would say they are not (and indeed randomness doesn't really help). In contrast, I would claim that the only sensible definition of free will is based on dualism: Many people seem believe there's some inherent aspect of them that is separate from the physical world and is the source of their self and will. If, like me, you don't believe in dualism, then the conclusion is that we don't have free will.
