"where you control" might mean getting a static IP and setting up a server at home. That can be a Pi running apache and use tools you bash together to convert you markdown into html. "content management system" doesn't have to be all the fancy, especially at first; a makefile may do what you want. "Site Generators" like Pelican and Hugo and many others exist to fill those needs too. "protection" is something you may want to ignore until you actually need it. How much traffic are you actually expecting, and how many enemies do you have that will want to block it?
