Unfalsifiable isn't the point. Non-explanatory is. All those other classes of theory have good (hard to vary) explanations.

You think sexual selection theory isn't a good explanation of behavioral sex differences?

It's a good explanation for non-humans. But explaining differences in human behaviour via genes quickly runs counter to human universality.

How is this distinguishable from blank slate hypotheses

In the same way as with actual slates. Saying their present content need not depend on previous content is not the same as saying they were initially blank, or initially identical.

The ratio of genetic determination vs susceptibility to environmental adaptation is probably variable and entirely genetically determined.

It's due to the laws of physics, isn't it? What's possible is what's not forbidden by the laws of physics.

If there is evolutionary advantage in resisting vs. adapting your traits, then this will affect the plasticity of your traits.

Ah yes, I agree. Some traits are very hard to change.
