There are 2 related but different questions here: are they worth it, and have any jobs we applied for cared about it.
I do have 2 AWS certifications. I’m not sure how much they cared, but it made things easier for sure (as j pointed out, it’s like when a company has some ISO/SOC compliance certification: it assesses some foundations so the time checking these parts is really reduced, if not completely removed)
For the other parts: are they worth it. This is more a personal feeling, but I still believe yet it was. In a nutshell, cloud vendors offering are so huge right now that one always focuses only on very few parts, the one they use on a daily basis. Studying for the cert exams forced me to do 2 things:
I wrote a much longer post about this shortly after I passed my second AWS certification medium.com/@sportebois/preparing-to-pass-an-aws-c…
Approx two years later I still believe it.
Another interesting question could be: Is it the best use of your learning budget (both $ and time)? and I might not be positive here. Studying for certs is a big-time commitment for "just" this, and carefully investing this time on other resources could have a bigger impact. But like any exam, the cert forces you to study continuously before the exam, whereas cherry-picking things here and there might make it more difficult to study with the same commitment level.
