[1] Referring to cosmological natural selection as a theory of the "fine-tuned" universe: https://en.wikipedia.org/wiki/Cosmological_natural_selection (a fun favorite of mine but not looking likely)

I think one lead we can have is that simulations are called simulations because they try to emulate the real world (the one simulations are running). By observing from inside the simulation what kind of input and reaction the "God" people has when we output something, we might be able to understand the "real" world better. It's like the "people" in the Sims game -- given they are of their own mind, they can figure out some rules of our world.

But then how can we jump out of simulation to really really figure it out?

It seems strange that a superdeterministic universe constrains certain kinds of phenomena to statistical distributions for no obvious reason.

Free choice is a completely different issue, and I'm not even sure it requires quantum theory. Clearly we have the illusion of free choice, but just as obviously our choices are very heavily constrained. In fact the constraints pretty much determine personality. And there's plenty of evidence from psychology that if you you have an accurate model of personality you can manipulate someone's choices without them being aware of it.

So I'm not seeing what quantum theory adds to this. It seems to assume consciousness is quantum and works back from there. Which is a weak argument (IMO).
