Shoulder position

I just want to confirm,

I read in the HS forum a discusion about shoulder position.

During shoulder flexion, or when we're inverted should we rotate the shoulder internally?

Or just let it be in neutral position?

If rotate internally should the pit of the shoulder Face to Face or we can go beyond that?

Thank u

One more thing please....

How wide we place our hand?

Shoulder width? Or wider? Or is it depends on our preference?
