I agree with several points of your opinion, I think this comparison between Caçadora and Naho is wrong
the hunter has suffered several defeats in the past, her spirit is destroyed, she does not fight for her own good, but for the will of others. She is not proud of her sole purpose which is to be a tyrant's weapon, she only joins the protagonist when he proves to be a good leader and kills herself when she sees him as another monstrous tyrant.
Naho was never defeated and many tried to overthrow her and take control of the pack, she always fought for herself, she was always above everyone, the strongest warrior among all wolves, within a group that values strength above all else. . . . . . . . . . . . . . . . , her pride is monstrous, then a dragon came and she lost everything.
The huntress has already lost everything, she has nothing left to lose by joining the Dragon, he is trying to recover some of what was taken from her by her ancestors the ancient Dragons, she sees the current Dragon as something to give purpose to her life which has always been without purpose.
Naho had all the strength and respect of his race and lost it all overnight. The Dragon is an obstacle. The only way to recover everything you lost is to overcome this obstacle. Imagine how humiliating it would be to become the consort of the being who destroyed your life, and the pack would never accept her, she would be a submissive coward.
As much as I like Naho, it's a difficult puzzle to convincingly cast her as a consort.
