Minimal amount of noise reduction

A lot of noise reduction.

Not really only from fiberglass insulation unless also did something
about separating studs, etc., ...

I agree, you only get minimal noise reduction unless you build a wall
with 2x6 top and bottom plates and 2x4 staggered studs so you have 2
isolated drywall panels on each side. This is the proper way to build
a sound-reducing wall with normal building materials:

Top down view of staggered 2x4 studs on 2x6 plates, then you insulate
for maximum quietness. This is a great method for home theatre rooms,
furnace rooms, etc.
