Is the CMP certification actually worth it for a mid-career marketer?

I've been in B2B marketing for about six years and my manager keeps bringing up the CMP certification as a way to formalize my skill set. Honestly, I'm on the fence. The study load looks significant, and I'm not sure whether the credential carries enough weight in job postings to justify the time away from actual campaign work.

From what I've read, the certified marketing professional designation covers everything from strategy and analytics to digital channels and consumer behavior. That breadth sounds appealing, but I wonder how deeply it tests any single area. Does the exam lean more theoretical or are the questions scenario-based?

I did find the CMP practice test hub here which has been helpful for gauging the question style. Still, I'd love to hear from anyone who's already passed — did hiring managers or recruiters actually notice the letters after your name, or is it mostly an internal confidence boost?

Also curious whether the marketing certification helped with salary negotiations. Any data points, even anecdotal, would be really appreciated before I commit to a study plan.
