What is a good language to build a modern website in? [closed]

I'm looking at putting together a website that needs to have the following requirements.

1. Display information with graphs that take data from AWS RDS database.
2. Looks nice and modern (I think my friend designs websites in elementor?).
3. Can scale up its hosting requirements as needed - probably hosting side.

So what's a good language to go in with? Preferably something modern and well designed, taking suggestions!
