I think everyone takes until mid 20s/early 30s to become socially functional. I went to normal school, and even day care (parents both worked), and I didn't totally overcome my social anxiety until I was 30 and had kids of my own. I still feel like I could do better.

Of course, I'm slightly biased, as we're probably going to end up going the homeschooling route. We were 50/50 before, but with COVID, we joined our church's homeschool coop, and because of that both our daughters are better socialized than peers their age. They meet every day. Older kids even meet up without their parents there (although there's always someone watching). Parents also hire tutors as groups, more like a 'pod' than traditional homeschooling. I think it'll work for us
