Definitely ‘pages’ not ‘posts’.
I need to display the content, not just their title.
The thought process behind displaying them based on their templates was that I only need the content from pages that use a certain template. However, I sat and looked at it and I think that, with a bit of reorganizing, I would only need pages with a certain parent. So, that would be two different ways of filtering the pages that I need…If that makes sense.
