Good luck on the checkride. Yes FBOs for insurance purposes will require a checkout prior to letting you rent an airplane. After my PPL I wanted to fly a Skyhawk at another FBO but I had to get a checkout to rent it even though that's the only plane I had been flying for the last couple of years. Of course if you decide to jump to a different make and model, it is not only a requirement but would be very wise for you to obtain a thorough checkout. Good luck again.
