Which programming language should I choose for my career as a career changer?

Hello,

The question here is explicitly directed at programmers who ideally already have a job.

I wanted to ask which programming language is good for career changers to get started in their professional life.

I now know some Python and SQL.

There are YouTubers or websites that promise you that you can find a job in just a few months by taking their course, for a fee of course.

But I want to do it on my own, so my question is:

Which programming language is best suited for getting a job in a short amount of time? Of course, you won't have all the know-how in such a short period of time, but you should continue to develop your skills on the job. Of course, I know I won't be paid much.

And which programming language should you start with for which career (e.g. with SQL you can become a data analyst). So what can you recommend?

And do you know any good books or YT channels?

And what kind of experience did you have in your first job? What was the first programming language you applied for, and what was it like when you first started learning and on your first day on the job as a programmer? Do you have any tips for me?

Finally: Please refrain from making unnecessary comments. I know it's time-consuming, but I want to get my point across. I'm not a script kid either; I really want to learn. I'm happy to respond to your comments.
