I think the state should take care of :
-Free and universal education
-Free and universal healthcare
-Army, firefighters, police
-railways, subways (highways can be private and work fine)
-energy generation, oil exploration etc

And leave the rest to the market.

I also believe there should be anti-monopoly laws

Basically, the state should make capitalistic competition fair, by allowing the sons of poor people to get a good education, and if they are smart enough, a title, and get rich, capitalism is the best we have, but the state is there to make capitalism tolerable.
Otherwise, eventually the peasants will kill the rich people
