Again, I'm not an astronomer. Of course at this rate I'll become one.
I don't see any significance to Cepheid-Parallax agreement since:

The mean standard error of a single Hipparcos parallax measurement was
1.5 milliarcseconds (mas) - a larger parallax error than most of the
individual Cepheids' parallaxes. The largest individual parallax was
7.56 mas for Polaris, our closest cepheid, which unfortunately is
almost certainly a first overtone pulsator and required special
treatment.
