I say this with sincerity, not judgment: You (presumably) made a choice to start a family and be a homeowner. Why not embrace it?
You can always yearn for another life, but if you pursue it, that usually means giving up on family and and home time. Is that worth it in your heart?
I knew a few older men who focused on their careers and personal aspirations more than their families, and it didn't turn out well for the families. They found success and prestige outside the home, but also turned into lonely, somewhat broken men later in life. I also know a few men who decided, fuck it, I'm not single anymore, and there is no more "me"... it's the family life now. They dove headfirst into dad-dom and loved it for all its challenges. Nobody outside their family really cared, but so what? They were happier.
I'm not saying the family life is for everyone. I'm nearly 40, unmarried, no kids, no house, a lot of freedom. I spend my years exploring, working, learning random hobbies, traveling, going back to school, backpacking, etc. But frankly a lot of those are young people's activities, and I'm out of place everywhere I go. That's okay by me though, because it was my choice to live this life. I'm now in a long term relationship with someone with similar life desires. That might make us more outwardly focused than homebody couples and families, but they don't find us that interesting because they have their own lives. We also don't spend too much time thinking about their families and private lives.
It's just different after your twenties. People tend to settle down and become less adventurous.
Sure, there are people who manage to juggle work and family and climbing Everest over the weekend, but they're pretty rare and usually very intense, for better or worse. That doesn't sound like you.
It's your choice whether to have a midlife crisis (lol), but if you love your family, maybe just try to find some fun hobbies to do with them? Go camping. Try tabletop games (many are wonderful these days, not just like Monopoly and Chutes and Ladders, but hundreds of new excellent titles). Take them skiing or biking or rafting. Start crafting projects, learn to 3d print or blacksmith or crochet. Play some D&D. There are many things you can develop an interest in without giving up the life you chose. Just find things with a limited time (and time away) commitment if you want to keep the family close. There's still a lot you can do in 2-4 hours a week, especially together.
