Wiki/Knowledgebase/Information Sharing

You can use a Modern Site which serves as a Howto Wiki and publish all your articles as Modern Pages and use something like a highlighted content web part which can showcase your articles in the layout you prefer like cards or carousel on the homepage. 

Modern Pages have a powerful interface for creating articles than classic with building blocks like sections,spacer, body and header where you can easily drag and drop content between sections and fill in your colors for each section to stand out.

Everyone can follow the site and easily access the content from SharePoint Home or can be added as a tab to Microsoft Team.
