It seems like there’s a lot of ways to go about this that may be overkill, so I’m curious which may avoid that.
Low maintenance in this context is aiming for moderate technical knowledge/setup, lower cost, and portability in case you need to migrate your site and so minimal hassle in that process.
Really depends what you want to create but there’s nothing wrong with just writing html and css. They’re as portable as you can get.
If you’re planning to do a lot of editing/posting then a static site genarator would be the next best thing as again you just end up with html and css which can be hosted anywhere. The generator can run on your system. Most are powered by markdown files so the content can (with little work) be migrated to another generator.
Beyond this you’re starting to get in to cms or other complex systems which i think is out of the scope of your question.
