Do bear in mind that all the components have to be the same grade to work together. So for CAT6A cable you can require specific CAT6A connectors with metal shielding, for CAT6 UTP you want CAT6 UTP connectors etc. it does make a difference. And likewise if you buy patch panels or keystones, make sure you buy ones that match. If you’re unsure, buy everything from one supplier and ask them to make sure everything is compatible.
CAT6A is not nice to work with, if you’re doing it right. And you really, really, really don’t need anything more than CAT6 or even CAT5e depending on your ultimate ambitions to run very high speed traffic. I regularly quote customers for grandiose requirements (their idea, not my recommendation) when all they actually need is CAT6.
