OneNote would appeal to me if it had the sort of "go find all my todos across this notebook" feature that OrgMode provides via the org-agenda.

AS is, I've never found it super useful. j

Viewing tagged notes has been in OneNote since 2010, not sure what you mean. ToDos are a built-in tag type, but you can also create arbitrary other ones and filter based off of those.

I mean individual items within a note, not entire notes.

I'd want to a collated set of all the items marked as "to do", ideally with due dates, in a "virtual" page or view of the data.

I understood you, that's what this does. See the quote below extracted from the link I previously posted. Note that the page it autogenerates is post-filtering and works the same way for any tag (built-in or user created). The summary screen is usually enough for me, but the full note page is nice sometimes because you can annotate it just like any other page.

"If you want to view the tag search results as a notes page, click the Create Summary Page button at the bottom of the Tags Summary task pan."

Huh, interesting. Doesn't seem to be an option on the Mac version, and I don't think there was this option the last time I tried to do it in Windows, but I'll admit that was a while ago.
