What we have here is a minimal, though complete instance of the cmSlate System. There are a number of templates available for page types such as an Image Gallery, Links, Directory, Calendar. There are Accordion style templates, Grouped templates where the posts are divided by Types, templates that show them ungrouped (but filterable) like the Journal. Custom types can always be developed.

cmSlate is crafted using Bootstrap 4, so it's mobile-ready. This will make Google happy. Getting more hits from Google will make you happy.
