I am actually thinking the ACF Pro Plugin might do the trick with the Options page allowing for global values https://www.advancedcustomfields.com/add-ons/options-page/
To clarify – this is for a newspaper. The homepage has sections where the editor can pick where different articles go. The articles displayed on homepage reference posts that are articles. The front page education section has a custom field ($front_page_eductation_section_related_post) where the editor can pick which article (post) he would like to choose to highlight for that section. There is another page in the site that is entirely dedicated to Education related articles. It would be great if the main article displayed on the Education page reflected what was chosen for the Education section on the homepage (ID=8).
