I’m thinking about building a desktop with one of my kids and I would really prefer to put Linux on it. My wife is not a fan of the idea, however.
I’m wondering are there any good Linux distros/utilities for children that include parental control features and things like that? And that are easy to use for a child who has only used basic Chromebooks in the past?
For reference the child is under 12.
In that case, I agree with the others and say leave this up to the router - not only is it far more easier to set up, it gives you/your kid the freedom to switch between distros/OSes, and you can even swap computers without worrying about having up the controls all over again.
A friend of mine was in the same situation as you (he’s also a Linux nerd), and he ended up with the router thing, and after extensive research, he decided to get a Synology router as it had all the features he was after (mainly limiting access times, monitoring and reporting).

And for extra filtering, you could also set the upstream DNS on the router to a filtering service such as Cloudflare for Families, AdGuard DNS Family etc.
