will the GT2210/11 work with a 10x4.7 prop?

You should watch the Flite Test beginner series. One of the episodes shows you how to choose motor, prop, esc, and battery. They all have to be considered.

But to answer your question...

According to the specs for that motor (I Googled it), the largest recommended prop without a gearbox is a 9x4.7.

what motor is the beef?

"The beef" is just a nickname for a "more powerful motor". What type of motor it is differs depending on the model.
