Which has more opportunities? (Short road to starting?) React, Vue, JavaScript, Python? [Front/ Back-End]?

So far, I know the basics of HHTML, CSS, kinda Vanilla JS.

Then also I know well,
React and Vue.

For styling I know:
Css, bootstrap, sass, Vuetify, Material-UI, styled-Components

I’m getting the hang of Python with the basics. I’m at the point of creating a Dictionary and other containers, and calling, getting data….
But, it’s not at a “you can see it” point… other than in the console….

When do you start seeing data or movement on the page????

Which should I focus on learning the most, as well as opportunities?
