My Dad (ENTJ) used to be the definition of this. As I was growing up, he was always very goal oriented and went after success; he also took fabulous care of his toys, but he was not nearly as involved when it came to his family. Every chance he could, he wanted to find a sitter and do fun things "without the kids". As a parent, I understand the importance of this, but it was a constant desire of his, it seemed. We did do a lot of things as a family, especially during the summer, but it was always on his terms. Those family events are still a tradition even now, but they are still always on his terms. He's a bit of a control freak
As he has gotten older, he is far more loving and family oriented; however, his dreams have been reached. So, I like to think of it as age maturing him, but the truth is, he has already accomplished what he's wanted for himself and NOW he has the time to focus on family. I suppose late is better than never though
As for my ENTJ Husband, he is not like this...I think enneagram and the balance of the person has a lot to do with variations in personality, especially when it comes to things like this.
