That doesn’t make sense to me. If larger objects move slower, don’t they move faster relative to the (accelerating) reference frame of the container?
Also, conventional wisdom has it that shaking (temporarily) creates empty spaces, and smaller objects ‘need’ smaller such spaces to fall down, and thus are more likely to fall down into such a space.

Yes? But so what? The relevant interaction is between the peanuts and the Brazil it's.

Right, but preferentially under the larger Brazil nuts.
