I’m going to break down that list of technologies you posted:
C#: not required at all unless you’re doing (or want to do) Microsoft stack specific development (which is .NET Core and SQL Server)
Python: also not required at all unless you want to do Python web development (with Flask and/or Django)
Java: not required unless you want to Java web development (with Spring, which has a steep learning curve of its own)
Angular and Vue: if you already know React, there’s not much point to learn these. You don’t really need to learn/know two different front-end frameworks/libraries, let alone the top three. And knowing React puts you in a better position to learn Angular or Vue if you need to do that later on for a job.
PHP and Laravel: not required at all if you don’t want to get into PHP web development.
Next.js: this could be useful to learn assuming you know React well, since a lot of companies have been starting to use it recently. It’s more of a React-based back-end framework - it does something called SSR (server-side rendering).
MySQL: well SQL in general is useful to learn for any developer, even if your goal is only front-end. But SQL is as simple as learning HTML, and you can learn it in a day.
GraphQL: not essential to learn, especially for just front-end development. Essential if you want to get into full-stack/back-end though.
AWS: not really essential to learn when you’re starting out, but should learn at some point. Can be learned “on the job” in your first job too.
It further needs to be said that C#, Python, Java, PHP, and JavaScript are all general-purpose programming languages so it’s not necessary to learn more than one of them at first. You can stick with JavaScript and be able to find a job with just that.
Also Python and JavaScript are extremely similar to each other. Any good company worth working for should or will know that.
