If it was a wood framed storage shed, that "might" become a shop; I would add housewrap, to the vertical walls, BEFORE sheetmetal was screwed to the exterior walls.

The interior insulation and vapor barrier could be added later, to walls. {I assuming a person would use a ceiling, for a shop, attached to bottom wood trusses, that could all be done later, also.}

Edit: the "Block-it" brand is what 2 popular You-tube wood post frame builders use.
