What to put? CMS, WIKI, other?

Question

CMS

On the local network on the IIS server, you need to organize something like a working library / wiki / notebook. So that users can enter the site, search for information by tags / sections. Create some of your own records with formatting and inserting pictures through the clipboard, tracking versioning. The information in the records can be anything, from a copy of the letter / order and ending with pieces of when. I tried WIKI Roadmap, tags, search and sections suit users, versioning also suits, markdown does not suit and there is no inserting pictures through the clipboard, I want WYSIWYG. Advise where you can find a beast with such functionality? Or at least in which direction to look or how such things are called?
