What kind of privileges should more mature children receive, if any?

Ma

If you have a child who is more mature and trustworthy, what sort of privileges would they be granted? To what extent would you trust them? Sorry if this is too general and open ended.

I’m not really sure how to phrase what I’m asking. I should probably include examples but I want to keep it somewhat open ended. For discussion’s sake, what type of freedoms would you allow? How much independence would you try and foster? Just for a point of reference, we can talk about ages 8, 14, and 17.
