I actually have more experience with Hugo, but my co-worker swears by Ghost.  So it’s just a matter of preference and the templates.  

Regarding LibreOffice, that’s fully free and open source, so there should be no privacy issues.  It comes with most Linux distros 

 many thanks for feedback

meteoric learning curve right now - like pig in the proverbial. couldn't be happier
