The content you are looking for is not a Static Block but a page. The shortcode for static content allows referencing any static block OR page ID/slug. For this situation I needed an exact replica of the home page so I could attach a different sample header. Rather than duplicating the page and keeping up with to copies for any changes/updates, I simply added the static block shortcode. The page you are looking for is the “Home Page”
A good solution to things like this is to create your own content, pages, layouts, headers, etc. and assign them where you need them. Use the demo content as a reference, but do rely on it too much.
