I think molinism as described by Craig answers the justifiable questions open theists have. Not gunna type out details on this phone but I would second that Craig has a plausible theory that isn’t deterministic like Calvinism.
I'm exploring the topic more than I have previously, though I remain unconvinced it's correct. An intellectual much smarter than I whose scholarship I respect, Dr. William Lane Craig, rejects Open Theism, and so I have been looking at some of his work trying to understand why:

I see why Molinism appeals—it avoids Calvinistic determinism while keeping foreknowledge. But Open Theists argue it still fixes the future since God selects a world where all choices are pre-known. Instead, Open Theism holds that some aspects of the future remain truly open, allowing for real-time divine action and genuine freedom.
