A typical home user will have a /56 of GUA, or maybe a /48 with some ISPs. Anybody who knows enough to figure out how to set a ULA can figure out a /64 from their GUA space that's not being auto-assigned by one of their various home routers. So if that's the way you want to do things, it won't cost you or your ISP anything.
Your local home network topology may not allow easy choice of a /64, if you have multiple actual subnets - if it all fit into one /64, why did you need/want that /56 or /48 in the first place?)
