I know, it seems like I will never finish building my website. And now with deciding to move to WordPress (hopefully permanently), it seems like it will never get finished. However, the one good thing that WordPress offers over basic HTML, is ease.
While WordPress itself, or rather designing and coding on it is a lot more complex, it actually is simpler in regards to “end-game". No need to add the same code to all pages, and of course there is ease of adding new pages, posts and media from anywhere without needing an HTML editor.
