I’ve used it with Python for data extraction and visualization last week. It worked worked surprisingly well 90% of the time. But when it failed to produce the code I wanted, it was difficult to trouble shoot and find a way around.
It helped a lot to break the tasks down as much as possible. It also remembered stylistic guidelines from several prompts ago

I’ve failed to get that to work. How do you actually get additional languages?

I second GitHub Pages! I host a professional website/online CV there with a dot com domain for less than 10€/year. There are Jekyll templates to do that or pay someone to make you some custom CSS and Html that’s easy to maintain.
