Connecting with an employee of PMI

I am a program manager (title is sr. program coordinator) in the department of radiation oncology at a large hospital/ cancer center. The largest part of my job is planning and executing ~5 annual national conferences for doctors. I also run the department's websites, social media, video projects, and newsletter. I'm responsible for compiling annual reports on faculty activities and other metrics. And, I manage other educational programs, visiting lecturers, internal communications, awards, philanthropy efforts, community outreach, and internal department events.

Given what I'm responsible for, are there ways that getting a PgMP certification would help measurably increase my value to the company/ specific examples? How would a certification help with planning educational events, marketing efforts/ content creation, organizational skills, reporting, and even community outreach/ DEI efforts?

Right now, my boss's comments are that he sees the value in being a PMI member. But, not a big difference in value between membership and the $800 verification. My department definitely has the budget for this, it's just a matter of measurably quantifying and explaining why we should do it. As I move forward into my career, I'm hoping to move away from projects and more into the program space.
