Are certifications worth it while job hunting?, hotel front-desk agent here

I am considering a short certificate to improve my chances as a hotel front-desk agent. This is my first time dealing with any of this. I am unsure whether employers value it. Which ones are overrated?

A hands-on course with a project helped more than a purely online one.

Check a dozen job postings first. If most ask for the same certificate, it is probably worth it.
