Same here, more or less. For what it's worth I was pretty strict about bed-times, about them helping out at home and in school, usually had a plan for the day that they might contribute to, ate meals together with us all eating the same food within reason, emphasised politeness and consideration of how their behaviour might impact other people, gave them their own space and then the basic building blocks of sleep, fresh air, exercise and good food.
But I also emphasised empathy, didn't bitch about other people in front of them - so no castigating of other people's parenting, or using terms like 'snowflake' - and if we saw other kids kicking off I'd just say that they must be tired. When mine got overly emotional or were struggling with their behaviour, I'd (as calmly as possible) tell them it would be best if they had some time alone until they felt better, not that they were innately bad or naughty.
One thing I didn't do and can't stand is when parents say 'you've made mummy cross' which I hear a lot. It's not about mummy, it's that your child probably doesn't actually want to behave badly. So I'd say act with surprise and some sympathy if they're acting up. If you've laid good groundwork in terms of respecting other people they'll get it.
It's hard when there are public figures such as Trump and Boris Johnson behaving so self-indulgently, breaking the rules, being obnoxious and so on.
I wouldn't go all out in making a plan to be laying down the law - in my experience that doesn't work. What does work is setting a good example so your kids learn how to live with respect with other people and in the world so they come to understand that they're part of a family and part of society and their behaviour has an impact on themselves, you, and everyone else.
My dcs are teenagers now, and generally polite, considerate and helpful. Who knows what's coming down the line but I really think the emphasis on being respectful and helpful as well as sleep, exercise and food has set them up pretty well (for now...)
