Title: Sanity check on a simple hard clipping switch arrangement

I'm 99% sure this is the dumbest question of the day, but these two arrangements of an ON/OFF/ON in relation to a pair of hard clipping diodes are functionally identical and both "correct", right? The objective is center disconnected, one side connected through a limiting resistor, and the other side connected directly.

Yes, identical. Direct, NC, through limiting R.

Even simpler is to permanently connect the resistor and just short it with one contact of an SPST switch

Not the same. You lose the option of "no clipping".

I was following the OP's schematic but his text says "ON/OFF/ON", so, not the same in that case.

With the above arrangement, you may notice a volume change between bypass and diodes. At least, this is what I found so, I wired a switch like this to overcome the issue

Vary the resistor value to suit the diodes
