My order of priority for my kids:
1. Get Enough Sleep
2. Eat good food. We don't do Juice or Soda at all. Chips etc. are ok once in a while.
3. No devices. My daughter started getting hooked on to Ipad and one day, we went cold turkey and put it away. She only gets to watch TV now. No more eyes stuck in an Ipad.
4. Dinner ON THE TABLE. Yes, this is so hard these days. We get lazy. But we have tried to enforce this and it has done wonders.
5. Talk to them. Teach them a few things while you interact with them. Give them chores to teach them the value of work. I have a simple one for mine: Turn on the porch lights in the evening. She loves it as "this is my job". Sense of ownership and responsibility.
6. Teach them to have empathy and how to treat others. This is so important. Don't overly reward them for good behavior but always say "You did a great job. I am proud of you" and that's it. Don't glorify it.
7. One activity. For us, it is Swimming. But you could choose any really.
After this (already a lot, isn't it) , it is mostly "let kids be kids". Depending on their mood, our availability and the day, we can do outdoor activities, biking, playing in backyard or go for a drive. No pressure of planned activities. That's it for me. My wife doesn't quite agree but I have been able to keep it like this for a while.
