Is there some URL I could visit that qualifies this?

I'm not doubting you, but I would like to have a mental model of roughly
why and how 64-bit mode benefits a system.

Leaving aside any x86 architecturable hobbling that may be cleaner in the
emt64 world, I would have naively assumed that (absent a need to access >4GB
of RAM or mmap >4GB of a file) 32-bit would use physically smaller
instructions and generally require physically less bandwidth.

Presumably these presumptions are wrong or misleading; I'd like to know
how.
