Yup, it can be bred in SWSH, if parents bred while holding Everstone, it's offspring will also be of the same regional variant as the parents
So the only real ones to worry about, is: if the game of origin is SWSH, and the base regular variant evolved into a regional variant.
(For example, as of time of writing, SWSH Koffing have to evolve to Galarian Weezing, not Kantonian Weezing)
