stat doesn't come close.
I wanted the automatic-multi column output of 'ls' like "ls -s" gives, 
but instead of the disk-space-allocated number as 'du' would be
sufficient for, I wanted 'byte' output -- like the default output of 'ls'
gives.

By default, ls gives you names, or with -l gives you bytes.  If you want
a short form that gives you bytes+name, the obvious attempt would be
use of -s with a flag that would say to display bytes.

This rare use case? Having a file-list command that 
displays filename+size in a compact form seems one of the
top use use-cases.  Yet that seems to be missing.

The default of ls -s should be to display size, not allocated blocks, since
if you want that, 'du' is what first comes to mind to find the
diskspace-used.
