Yes.  In the presence of grafts, run “guix build PKG”.  That always
gives you the store file name of PKG, 100% reliable!

I regularly do things like:

  ls $(guix build PKG)/bin
  find $(guix build PKG) -name …

But note that ‘guix build’ returns one file name per output, so in case
of multiple-output packages, you have to pipe its output through ‘head’,
‘grep’, or similar.

If you want a variant that does that without building/downloading it,
it’s also possible, though not as easily from the command line.
