What strikes me about this thread is that build time is usually a time
of needing to cut costs, not to splurge on everything you dont need. I
would therefore take a 2 phase approach. Work out what you ideally
want, but only put in the things that need to go in, plus the things
that will enable the rest to be put in some other day.

BTW you only need 2" of height for isolated ceilings, the 2x3 or 2x4
for the ceiling can go between the floor joists. Fibreglass or similar
on the ceiling will damp resonance and improve sound deadening
significantly too.

1"x2" counter batons under the ceiling joists to reduce contact with upper
floor. Then rockwool pads between ceiling boards and joists. Fibreglass
is useless between floors, use high density rigid Rockwool.
