First of all, /32 is the default allocation you get without justification,
right. So if you justify, you will get more. Do a proper justification
now, not in 3 years, so you're on the right track by trying to find out.
If you want a big subnet, planning to hand out /48 to everybody will give
you a lot of addresses, increasing flexibility down the road.
Personally I advocate handing out /56 to residential and /48 to business.
This just seems like a reasonable compromise between "should be plenty for
99% or more of the use cases" and let's aim for the sky. /60 seems short
sighted for residential.
