If you want to outsource it, I can agree that the easiest way is to provide a simple interface for the other party. That's where a CMS like Wordpress would make sense.
On the other hand, if you want to have more control in the long term, I can recommend to use Hugo [0] as a static website generator.
They have plenty of themes [1] to choose from. You can still adjust it with basic knowledge in HTML/CSS. Afterwards you can chose where to host it. You can use Github Pages [2] for free or pay for a service like DigitalOcean [3]. I wrote a technical cheatsheet [4] on how to setup your own website with these ingredients.
