While developing the archive.html template file I decided to extract the navigation menus
into separate template parts.
I decided to try two methods.

For the footer menu I extracted the navigation into a footer-menu template part then added this to each template, 9 in all.

<!-- wp:template-part {"slug":"footer-menu","theme":"fizzie" "className":"footer-menu"} /-->

For the header-2-columns template part I'd extract the navigation into header-menu, including this template as an inner block. Fewer changes.
