Continue with grad school or just work?

Hello all, maybe you can shed light on what I have been mulling over lately. I am finishing up my undergrad degree in SCM this year, and I am getting antsy- for lack of better word. I have a stable job in a brokerage department with opportunity to take on more (management has brought this up multiple times, it seems I am valued beyond my personal measure of skills). However, I fear lack of industry relevant skills, I don't use SQL or Power BI kind of things at this job so I am wary of not being prepared enough should I need to transition jobs. Supply Chain as a field is definitely a good fit- but I would like to move on and up. I have been receiving Grad school emails and really wondering if a masters is the way to go? Any relevant thoughts or experiences would help me build a pros/cons list as I near the end of this year.
