I've always imposed strict limits for myself. I don't know that I thought it out so meticulously as you've done. But from the outset, I refused to let technology come between me and genuine connection with my little family.

I always log off my desktop around 4pm. My phone has no games, period. As for social media, I have only added the Medium app to my phone. However, I do not read stories on my phone. After 4pm, the only thing I do with that app on my phone is check my responses and reply. Other than that, I text-chat with my son and his partner. If someone calls, I'll talk to them; that also is usually my son or his partner.
