Without going into specific working hours (because these can vary from project to project), it is important to keep in mind that you will have to put in long hours at work. I would say it is quite common to work the hours you mentioned.
However, since you mention that what is important to you is time with family, there's a few ways I have seen people make this work.
1. Focus on local projects - yes the hours are still demanding, but at the end of the day there is usually flexibility around where you can work from after a reasonabe hour (after around 7:30 pm or so). Local projects will largely be in industries that are large where you are (e.g., finance in New York or Oil and Gas in Houston)
2. Make it clear to the team that spending time with your family is important - consultants are human too and they all understand that work is not the entirety of life. I have worked with many people who take a dedicated 1 to 1.5 hours every day to facetime with their family even when they are on travel studies
3. If possible work out flexible arrangements - there is a big push towards mindful travel in the industry, So if you don't have client meetings on Monday you can fly out on Tuesday instead etc.
4. Find mentors and peers in similar situations , not only will they guide you on best practices, often they can end up staffing you as well and give you more flexibility that suits you
All the best,
