One doesnt have to distinguish between Esau as a person and Edom as a people, the choosing or otherwise applies to both.
The Pharisees took a very dim view of Esau. It’s possible that Paul is giving us the Pharisaic view of Esau in the verses you cite in Romans 9.
The following quote is from John Gill’s commentary on Hebrews 12:16, where he tells us what the Pharisees thought about Esau.
<< ... Esau; to whom both these characters seem to belong: and this
agrees with what the Jews say concerning him: they have a tradition {w}, that
he committed five transgressions on the day he came out of the field weary.
"He committed idolatry: he shed innocent blood; and lay with a virgin
betrothed; and denied the life of the world to come (or a future state); and
despised his birthright.''
It is elsewhere {x} a little differently expressed.
"Esau, the wicked, committed five transgressions on that day: he lay with a
virgin betrothed; and killed a person; and denied the resurrection of the dead;
and denied the root, or foundation, (i.e. that there is a God,) and despised his
birthright; and besides, he desired his father's death, and sought to slay his
brother.''
It is common for them to say of him, that he was an ungodly man; and
particularly, that he was a murderer, a robber, Pawnw, "and an adulterer" {y};
and that he has no part in the world to come {z}: who for one morsel of meat
sold his birthright; the account of which is in Ge 25:29 this includes all the
privileges which he had a right unto by being the firstborn; as a peculiar
blessing from his father; a double portion of goods; and dominion over his
brethren: and it is commonly said by the Jews, that the priesthood belonged to
the firstborn, before the Levitical dispensation; and that for this reason, Jacob
coveted the birthright {a}, Esau being a wicked man, and unfit for it.

I can’t think of an occasion when Jesus agreed with the scribes and Pharisees. Paul apparently does agree with them on Esau.
