I’m not aware of any cell type with more than a few volts of potential. If we’re designing from scratch you just put fewer of them in series in each pack. There might be problems getting other components conductive enough to facilitate the needed power transfer at a much lower voltage, although now we’re outside of what I really know. If it’s 40V it shouldn’t be a problem.
While you’re at it standards for higher power DC would also be good. IIRC there’s a few in competition for EVs right now.
Good point. It’s probably an integer multiple of the (nominal? State of charge comes into it too) cell potential. Which is fine, as long as there’s another one that’s reasonably high but below the USB-PD maximum.

That’s what I thought too, initially. But then I thought that maybe there is a good reason for the specific 54.6V figure. But I didn’t dig deeper
