Query structure field of specific child page

Besides my listed pages, I have an unlisted page with child pages holding different taxonomies for structuring my content, most of the time saved in structure fields.

I’d like to query the content of these structure fields for select/tag fields etc. on other pages. I don’t want to query all structure field of all “taxonomy children“ but just one specific page.

How can I do this? I query tags from parent pages (with site.find etc.) all the time but don’t know how to select one specific child page (of a different parent).

Thank you!

One option would be like this:
