Dwarf boa with best temperament?

[Badatnamesbro]

Hey!
I am looking to get my first snake I feel in love with boa and found out about dwarf boas. I am looking for a snake that will get no bigger then 5 feet or 5 and a half at the most feet(I plan on getting a male) A snake known to have good temperament and not he picky eaters is very Important too. Care wise I don’t mind if they require a high humidity. Was looking into hog island (my local reptile shop breeds them) but heard they sometimes can get 6 plus feet.
I have looked into dumerils boa but am confused at size they on average are when adults.
Thanks.
