  The recent SH0ES determination of the Hubble constant, $H_0=73.04\pm1.04$
km/s/Mpc, deviates significantly by $\approx5\sigma$ from the \textit{Planck}
value, stimulating discussions on cosmological model extensions. To minimize
statistical uncertainty and mitigate sensitivity to systematic errors in any
single anchor distance determination, SH0ES combines Cepheids from various
observations, including those from Type Ia supernova (SNe Ia) host galaxies,
NGC 4258, and closer galaxies (MW, LMC, SMC, and M31), although this mixed
sample may introduce unknown or subtle systematic errors due to comparing
distant and closer Cepheids. To address this, we propose a subset excluding
Cepheids from the closer galaxies, retaining only the NGC 4258 water megamasers
as a single anchor, circumventing potential systematic errors associated with
observational methods and reduction techniques. Focusing solely on these
Cepheids yields competitive statistical errors, approximately $2.5\%$,
sufficient to identify a $\approx3\sigma$ tension with the \textit{Planck}
$H_0$ value. Our approach offers an opportunity to utilize optical photometry
with systematic uncertainty smaller than the statistical uncertainty,
potentially achieving higher precision than NIR photometry, given the lower
optical background. However, currently the optical photometry sample's fidelity
does not match that of NIR photometry. The significant Hubble tension obtained
is unrelated to Cepheids and we discuss other options.
