Is it better for natural resources to be state or privately owned ?

I’m not an economist, but I’m very interested in economics, and I am trying to invent my own economic model that would be something like social democracy.

Anyway, I am wondering: Is it better for natural resources (oil and gas for example, among other things) to be state or privately owned?

1. which gives a better economic growth? For example, in Norway, the government owned 67% of Equinor, the state owned oil company. Through that and high taxes, they achieve a good welfare state. But what if it was 100%? And does this harm the economy in any way? (let’s say if it was privately owned, would the economy be any stronger)

2. If it is privately owned, and people invest into the companies, would the government be able to profit off of it as well in some way?
