Yes there are, simply go to the link bellow and put in the search bar the key word Page or extra page, or basic page.... or pages... https://open.vanillaforums.com/addons
@caygri, to link a page on the top menu with Basic Pages, you can enable the "Show header site menu link?" option when editing a page. Alternatively, the Add Menu Item plugin will give you more flexibility with how links are arranged.
Basic Pages is very well suited for what you need. It is an "aaplication" not a "plugin". You would have to upload the unzipped folder to /applications and afterwards you can enable it in the "Applications" section in the dashboard
