If you use the equinoxes or the solstices you’re still being arbitrary because there are two of each.
January 4 is the day of the year that the Earth is closest to the Sun [perihelion] That would be a good date, but there will be those who argue for stating the year when Earth is furthest away.
That moment is the moment the Julian calendar restarts. It’s not arbitrary at all, and certainly not made so by virtue of it not being the/a winter solstice (your original statement).

Okay, but why would that mean that New Years Day not being the winter solstice makes it arbitrary to celebrate on Jan 1?
It’s arbitrary because there’s no moment that is the obvious beginning of the cycle.
That’s the very definition of ‘arbitrary’
