My gut feeling would be to use 2-unit cable management stuff for the
majority of the needs. It is far better to have excess capacity than
not enough capacity, IMHO, and it's nice to get the space now, because
if you decid you need it in the future after everything is wired...

Also, I'm not sure that I'd say that flat satin voice cable --
especially in bundles of 48 is 'much' smaller than UTP. It depends on
what flat satin and what UTP your using, but maybe a little over 1/2
the space requirement.

My $.02: If you have the rackspace to spare, use the 2U cable
management panels; if you don't have the rackspace to use the 2U cable
menagement panels, add another rack and use the 2U panels; if you
don't have the room for another rack, use the 1U panels

I would second Linclon's approach. I try not to use 1U managers a
much as possible. At worst, I'll put a 1U at the top and bottom of a
stack of a 2U-48 port panels, with 2U inbetween each panel.
