Happily, I am long past the publish/perish stage of life and use DT3 to compensate for brain-rot. I am not the GOTO source for efficient automation. I will post my list of links since you expressed an interest. But rather than spending the MANY hours to read/digest/streamline/implement these, I suggest you look into this course - devonthinkforhistorians.com and read one of the users’ blogs DEVONthink — Blog — Avigail S. Oren, Ph.D.. Possibly they have figured it out. I intended to take it but haven’t gotten around to it.
I also suggest searching Zotero/DT3, perhaps someone has a solution. I found these that may be pertinent:
forum.obsidian.md/t/dt3-zotero-and-obsidian/15537
GitHub - traviseross/Workflow-Scripts My Zotero to DEVONthink 3 workflow to seamlessly keep Zotero linked to attachments in DT3.
