Does it have parental controls natively or did you have to install something extra?

I would love to be able to whitelist which devices are allowed to access the internet during night time hours.

I do it the opposite way, disable my kids' devices at night, but I suspect your desired method would also be supported using native features. I have found LLMs to be very helpful in providing the right settings.

There is a plugin marketplace that provides more features, like ad-blocking. I haven't played with those yet, so I cannot vouch for them.
