Which would you prefer and why? (I know its different) PYTHON vs JAVA/KOTLIN

Which would you prefer and why?
Vue, React, Python,Django, Flask (concentrating on Python)
….
OR
Java, Kotlin?? Using Spring?

I’m trying to narrow down what is “needed”.
Styling can be anything, it’s always changing.
I’m not really liking styling that much.
I like creating objects and interactions, but I don’t like the styles of it that much.
.
So is Java, Kotlin good? Is it popular and needed?
