The most common thing I see is /64 if the end user only needs one subnet, /56 if they need more than one.
Brrzt, wrong. Neither the end user nor you know the answer to that question!
So the only sensible thing is to always give them a /56.(Actually, the IPv6 address architecture design was to give them a / 48. Think about it: We will run out of MAC addresses before we run out of those. But some people can't manage the cognitive dissonance coming from an address starving IPv4 world and then "wasting" all these 2^80 addresses. My parents, who grew up around WW2, were that way, too, and never could unlearn their "saving" habits. So the current "wise" thing is to allocate a /56, "wasting" only 2^72 addresses per customer. The only way back to a connected Internet.)
