My opinion is do what works for you. I restricted certain foods for my son when he was under 1 as I believe he doesn't need sugar (i.e. cakes/lollies). I still try and limit them a bit (he's not 2 yet).

We've been lucky so far with no allergies so our eating habits sound similar to yours. We do our best as parents, but it's also ok if our children grow up with other opinions. My parents were into "food combining" (not mixing starches with proteins) when I was a teenager. They claimed it made them feel better, but once I left home I went back to combining everything (I missed having cheese with pasta/pizza etc!).

So if your children end up eating differently when they leave home, don't beat yourself up In the meantime, enjoy the fact that they eat what you cook. The less stressing over food the better, I reckon!
