THIS!
I'm on Hugo now, and have used both self-hosted and .com (free) versions of Wordpress. Which of the 3 do you think I wrote the most when I was in it?
Yeah, free wordpress is limited, if not open-source, blah-blah-blah. But it's a few clicks to create, easy to write the posts/have drafts/change theme. And I would argue that having limited themes on free can actually be a positive thing. You have a few options, chose something and start writing.
Having to write in any other editor (to have grammar checking), then paste on VS Code, deploy... it just takes more time. And this is without managing any media, which I just upload to imgur and use the link...
