We've seen him interact with humans in canon, and there was an anime episode where he greeted a random human customer in a German cafe. As with other nations, he was shown to be very strict with them. I think he's especially strict with soldiers, because he considers being obedient and following a tough regimen as a part of their duty just as he considers it a part of his own duty.
But he does care about them and he's as polite with them as he is with other nations, though he knows they're humans and he can be blunt about human limitations. Usually that's for their own sake. Back during the war, he'd also have a drink with them after a long day of work and when they were off-duty he could act, relatively speaking, relaxed around them.
I'd say he gets as involved with state affairs as he can - it's his house and body they're making decisions about, after all, so his citizens and his health are involved. He has his own opinions about everyday decisions, but I imagine he'll be professional and either voice those objectively or only voice them around other nations. Ah, unless they're big decisions that'll heavily impact his home or his relationship with other nations.
And Himaruya stated he's good with children, too, if I'm not mistaken. I'll bet little children that are brave enough will run up to him and ask him to swing them around or if he'll carry them around on his shoulders and such. And if they ask properly, he'll do it, too. Let them hang off of his biceps and such. Still, I doubt he suddenly turns into a happy-go-lucky kind of person around children, and he probably doesn't spend all that much time playing with them.
