Hot take but honestly, none. They can be helpful to stand out on a resume but when I'm hiring, I don't necessarily make a decision based on the certifications themselves.
On the flip side, I am a big advocate of always learning. So what certifications do show is that you are constantly hungry to improve.
I've enjoyed experiences from 280Group, especially when I was first starting out and wanted to get a solid understanding of Agile as it relates to a PM. Some analytics certifications are good to in terms of helping you get a foundation for Google Analytics, Mixpanel, Amplitude or any others.
Nothing beats real-world experience. And if you don't have a lot, a couple of certifications can help you take it up a notch.
