Manually curate or dynamically aggregate pages by a specific page category in a grid or in a standard list layout.  

Create subpages on your website for your secondary-level menu, which can include a featured image.

Sub pages can include a right sidebar to call out related content above the fold. 

Create section pages without subsection navigation displayed and highlight content within a section, similar to a landing page but focusing more on subsections and less on featured and related content.  

Use Page to create Landing pages for your key sections of your website.
