Benefits of Masters of Ed vs. AQ courses?

Hey everyone. I am and I/S teacher in my 4th year of teaching with phys-ed and english teachables. I would like to further my education while I take my next year as an OT but I'm torn between completing my Masters of Ed and just doing AQ courses. Keep in mind I have no desire to ever be a VP or principal. Does anyone have experience with this and can offer some advice? Follow up question, if you suggest doing AQ's which ones are most beneficial for hiring?

TIA!
