That's by and large how I do it, although dpkg -S /path/to/program
doesn't require apt-file to be installed.

That's actually correct. LibreOffice is really by and large one big
binary with different "modes" for Writer, etc., and it is indeedn
libreoffice-core which ships /usr/lib/libreoffice/program/soffice.bin.
