Workday Tech Consulting - Which Practice should I go into?

I've done corporate FP&A for 2 Workday Implementation partners over the past 4 years of my career and I'm wondering what Technology Consulting practice I should transition into where I would be able to use my current technical/operations strategy skillset and expand on it in order to open myself up to Management/Strategy Consulting roles later on (after I go to Grad school for my MBA).

Practice meaning Workday FINS, HCM, Reporting, Time Tracking, Etc. (I would be getting certified in whichever practice before starting the job).

Any bit of advice helps and if there isn't a workday practice that falls into the criteria I laid out, then let me know so that way I can put my efforts toward another aspect of development.

Thanks Everyone!
