How to check signatures on apps, installers, and packages

pkgutil --check-signature macOSUpd10.14.1.pkg

this does perform validation and report the most informative result of all:
Package “macOSUpd10.14.1.pkg”:
Status: signed by a certificate that has since expired
followed by the certificate chain. Unfortunately, pkgutil doesn’t appear able to check notarization, at least in Mojave, for which spctl is still required.
