I’ve just shared a page with a friend (publicly) and noticed that the files that I uploaded aren’t visible on the public URL. Is that intended?

This is intentional, Erik. Files are not included on publicly shared pages.

Email links (unlike file and writeboard links) are included on publicly shared pages, and so emails may be indexed and cached by search engines.

Is there a way to quickly identify all public pages in a site? (sharing icon on “All pages” doesn’t discriminate between shared and public?)
