Some ideas for how you can use Pages are:

• Design with the Rich Content Editor (RCE): Add images, files, record or upload multimedia content, and embed external tools like YouTube, Khan Academy and other LTI tools 
• Content Selector for more: Using the content selector from the right-side you can add direct links to other Pages, Assignments, Quizzes, Announcements, Discussions, Modules or other course navigation areas 
• Make sure it's accessible: It has an awesome accessibility checker

More things you can do with Pages are:

• Easy to duplicate Pages from the selector in Module view 
• Use them for collaboration. Pages can work like collaborative wiki pages that students can edit, while allowing the instructor to see and curate the edits
