They mostly help generate clicks for the publisher, and to push someone's agenda (if it was paid for).
If it ever helps someone in a significant concrete way, that's a mere coincidence.
In talented HR these personality traits aren't used like that either, but rather used as talking points which make it much easier to get to know a potential hire than not having the test results to refer to. A good example of this is an old boss I had who scored a 0 on empathy in our organisational developed personality spin (because lets face it, these things are big business, and of course our HR consultants had paid an external consultant agency to develop our own). Anyway, he scored a 0 in empathy, and he's one of the most emphatic people I've ever known, but because the opposite was ambition and result orientation, and probably because it was his first leadership job, he had gone in that route with his answers. Now if we had taken the results to be factual rather than just a good baseline for discussion, he wouldn't have gotten the job but it was a good talking point. The tools themselves can also be very useful for getting team members to "bond" or at least get to know each other better. If you simply ask people what they think about something personal, some people will elaborate and give good answers because they are comfortable (and in extraversion) in those situations, while others will give you nothing. But if you base the talks on personality test results, you can very often get everyone to open up and have a good talk.
Obviously it's not completely made up either, there is science which shows different personality traits, but there is nothing that shows you're either or, unless you have some sort of disorder, in which case, you're probably more likely to switch than be of a single version. Sometimes people gather energy alone, sometimes they get energy from being social, and overall you're likely to be more happy the more of your time you spend in extroversion (as an adult anyway). It's also not something that necessarily tells you much about how people want to work, you can be a massive extrovert and still prefer to do many tasks on your own, or you can be an introvert and prefer to do your work as part of a team effort.
Unfortunately mainstream culture likes boxes. Like this article. Because you can be very sociable and still prefer to work from home. Maybe because you're young and used to being social online, or maybe because not having to commute for x hours a day gives you soooo much more time to spend with people. This headline probably gets more clicks than another article about how a lot of people prefer to work from home and the pandemic made them realize it. Interestingly, in my anecdotal life, a lot of the people who are what could be called very introverted tend to be the ones who prefer going to the office, because sometimes it's one of the social parts of their lives.
It also ignores the growing cultural divide of our clickbait ad-based economy that preys on fear and outrage in order to profit from everyone's misery by trying to sell them the latest plastic junk from China that eventually goes into a recycling bin and then shipped back to Asia where it's dumped into the rivers and ocean.
1) A era of the tech bro is waning.
2) Young workers are focused more on less alcohol in their lives, and more on living a healthier lifestyle.
