Since Molinism is Reformed Doctrine-Lite already, I’ll probably just stick with the latter and let God be the Creator however he wants.
Consider this - Molinism has an old-fashioned, pre-psychological, concept of us as “given” individual souls, and so Molina’s guiding concept was how “we” would choose in different circumstances God might create around us.
But in fact, “we” are the internal character we produce by the choices we have made in each contingent situation in our life. Sociologically (to think of the external determinants of our personalities) we are the products of our unique social situations in the real world. Then again, Molina knew nothing of the genetic component of our personalities, itself a contingent fact of the particular world that spawns us, and which again interacts uniquely and contingently with the choices we make from the time we make choices at all.
In other words, who we are cannot be disentangled from the world we’re in, because we are not created solely as individuals, but as social beings. That’s why sin, too, is a social as well as an individual thing - and why the race, rather than each individual soul, is “fallen.”
And that’s why, too, the crucial element in salvation is not a right or wrong choice about God by more or less deserving “souls”, but divine grace, which cuts through the contingencies and complexities of our existence and creates us anew, raising us from the dead:
As for you, you were dead in your transgressions and sins, 2 in which you used to live when you followed the ways of this world and of the ruler of the kingdom of the air, the spirit who is now at work in those who are disobedient. 3 All of us also lived among them at one time, gratifying the cravings of our flesh a and following its desires and thoughts. Like the rest, we were by nature deserving of wrath. 4 But because of his great love for us, God, who is rich in mercy, 5 made us alive with Christ even when we were dead in transgressions—it is by grace you have been saved. 6 And God raised us up with Christ and seated us with him in the heavenly realms in Christ Jesus, 7 in order that in the coming ages he might show the incomparable riches of his grace, expressed in his kindness to us in Christ Jesus. 8 For it is by grace you have been saved, through faith—and this is not from yourselves, it is the gift of God— 9 not by works, so that no one can boast. 10 For we are God’s handiwork, created in Christ Jesus to do good works, which God prepared in advance for us to do.
And hence the idea of God building creation around the individual choices of human souls has things the wrong way round,
…for it is God who works in you to will and to act in order to fulfill his good purpose.
Now, understanding how that works is probably above all human pay-grades. But it seems to me that it’s only when we say of such passages, “No, that can’t be right,” that we start talking about middle knowledge, Molinism-lite, or any of those attempts to give the human will priority.
