If you know HTML and Python already I would recommend going for something like jinja2 + flask or fastapi and try some htmx stuff no need to use everything you can just refresh the site at the beginning. This should be pretty beginner friendly. It really depends on what you want to do. I don't know much about Hugo or Publii. If you want to make an interactive website and not just a blog or static website I would advise you against using either of the two. If you want to get a job in frontend webdev I would advise you to learn javascript (https://javascript.info/) and some framwork like react also learn tailwind or css.
