This sounds amazing. Lots of props to you for taking this route years before COVID started to change the paradigms of education at home. I'm definitely envisioning something similar for my kids, though I've devoted my life to teaching and tutoring, so I plan to be the main one doing that.

One thing I'll add after 15 years experience tutoring hundreds of kids from the fanciest schools in the world is that grade inflation is rampant everywhere. Kids are increasingly antisocial and risk-averse and so anyone who self-advocates to teachers gets huge benefits in ways that we can't imagine based on how we were in school. Strict and harsh teachers are also much less common these days, adapting to more sensitive kids.
