Penny~~ Point taken; but from the semantic pov, can't help thinking you have overdefined the word 'posh' ···

Not but what it is one of those silly, imprecise, overused words, always with an overtone hostility - or at least irony; or else inaccuracy, as when applied to the future Mrs Beckham in her Spice Girls days; she was not the least bit posh in any sense, but was just taller & dressed a bit neater & looked a bit haughtier than the other girls.

Silly: as this word always is.

Remember the old joke; two girls with Welsh accents:

-"Have you heard about Megan? Getting married she is."

"Is she pregnant?"

"No."

"Oh! There is posh!"
