Good old fashioned fiberglass batts seem to do pretty well, and are
likely to be as cheap a solution as you're going to find.

SAB, Sound Attenuating Blankets, which are slightly denser than
standard glass fiber batts are a start.

Look at Flanking Paths: electric boxes back to back within a stud
space, gyp board not sealed at the edges, ducts that give a path from
space to space.

Not really.. but here are some old faithfuls:

I've been in some labs with sand-loaded walls -- nice and quiet!

I have vinyl siding over 3/8" foil faced polystyrene panels over the
plywood sheathing, 2x4 walls with fiberglass bats, plastic vapor
barrier, and 1/2" sheetrock. I can't hear vehicles going up and down my
street about 90 feet away. The only time I know I have visitors pulling
into my driveway is when the yorkie barks, or the people ring the door
bell. If I had my druthers back then, I would have had them put in 2x6
studs for better heat insulation. That might have helped my fuel oil
bills today.

2x plate with separation between plate and studs.  Alternating studs is
important. Foam tape at plate and floor(under plate and above plate).  Blown
in insulation....Water based.......Used in movie theater and honeymoon
sweets.......(foam that hardens then is shaved off.) Cheaper is batt
insulation.
Some wall we sheetrocked 2 layers both sides.....with stud separation
Yes, electrical, and such boxes need attention with spray foam....
Important aspect is the transfer of sound waves through solid material.
Avoiding this will lessen sound.
