IMHO, there is no way to tell. There are girls I knew who seemed what you would call competent. One of these is today quite helpless and codependent, another is extremely competent in the technical sense but also extremely emotionally abusive. These are just examples. And some girls who are totally not involved as teenagers get motivated when it’s their own family.
I have heard saying from a gadol of the previous generation that a girl’s Kibud Av Va’eim and tzniyus are her markers for bein adam lachaveiro and bein adam laMakom, respectively. I would only caution that you need to trust that the person that is giving you the information about those traits actually knows what they’re talking about.
Daven, daven, daven. Hatzlacha!
