I was unsure of how to post in Tips and Tricks, I’m not even sure if this is useful, if it is:
Zwebtz posted a solution to a similar situation, which lead me to a solution which I’ve seen a others posting over the years, and it helped me:
Breadcrumbs:
{{ (site.GetPage .Section).Title }} for the title.
For the URL {{.Section | urlize }}
et voilà.
Allows for easy breadcrumbs - one would simply need to put the appropriate title for the _index.md file of that section in the frontmatter.
Posed insoluble for me and this was a very clean solution, in my new-person opinion.
