Need help with Ethernet T568A and T568B

Hey guys, so I had an electrician come today and do some work around my home. Long story short, they said I needed to use a T568A Ethernet cable from my wall jack to the router. They said I could just get it at BestBuy but I can't find a 3' one anywhere online. Nothing specifies between A and B clearly. Anyone know where I can get one?

Long story: The ONT (Black FiOS box) in the garage was originally connected to a rented modem/router via a 568A ethernet cable. I wanted a direct line to my router in the family room. The electrician has since ran Ethernet to the junction box inside a closet in the next room over. In this box already existed cat5 or cat6 (not sure what kind was already installed in the walls) not being used. He continued the 568A connection all the way to the wall jack in the family room. At this point, when done, I was told that I'd have to use the yellow 568A Ethernet cable originally connected between the ONT and Verizon modem/router to connect the family room jack to my router. He stated that because everything was A, that the finally cord would need to be an A as well. He recommended going to BestBuy and getting a white 568A cable. I can't find these though.

What should I do? Do I need to have him come back out and strip the end and connect it all via B, and use my B cable I was previously using? Or do I need to purchase an A cable? If so, where?
