How much of a difference should I truly expect to hear from the two different barrel lengths? My main goal is sound suppression for this setup.

If you keep it at 4.5" the difference is 0. Your not going to hear a difference.
4.5" and below will keep most rimfire ammo under 1300fps subsonic regardless of the host weapon. I have a mkiv tactical, 10/22 and ar22 all with 4.5" barrels and they keep all 1300fps ammo subsonic.
5"+ is when you have rimfire ammo going supersonic.
The smaller barrel is to keep it smaller, and I think a big factor is that it looks cool.
I've owned and shot both 2" and 4.5" barreled .22lrs.
I stick with 4.5" barrels. I've also had better reliability with 4.5" barrels and slightly better accuracy.
Also, the mounting holes for optics are different on the silencer shop mark iv than standard mark iv pistols so you will need a silencer shop specific mount for it if you are mounting an optic which i am assuming you are, so that could be a decision factor for you as well.
