Hi @maceffy13
I think it’s better if you use a custom taxonomy instead. That way, you can set the categories for the landing pages. If you don’t know how to create it programmatically, you can try Custom Post Type UI plugin instead.
But if you still want to use the page link field instead, kindly check this guide: https://www.advancedcustomfields.com/resources/querying-relationship-fields/. That guide is talking about relationship field, but the logic should be similar.
I hope this helps 🙂
