Don't think about it too much. Most of the web still runs on plain old PHP and HTML. New technologies pop up every now and then but most people who do this professionally just want something that does the job and don't talk about "their stack" outside of work hours.

I've only recently come back to the world of web after doing mostly devops/backend stuff.

While getting on the JS framework treadmill might get other people hired, staying server side + Bootstrap kept me sane and productive. The only place where I spent an innovation token[0] was on htmx and so far it's been absolutely worth it.

Don't worry too much about all of the options.

Pick one stack and learn it. The concepts are all transferrable.

They're all basically the same, some are just more or less bad and some have more or fewer very-helpful libraries available. It's all doing the same shit, mostly in very similar ways.
