You might look into a Waldorf school, while not really conservative. Waldorf doesn't use a lot of computers, they use blackboards and write their own text books from a Teacher lesson. Think little house on the prairie. They study classic history, Norse, Roman, and Greek mythology and build their own bows for archery in the later grades. Our local school is on 81 acres of farm, timber & wetlands. There is some hippy type stuff that goes on, but it is more about letting the child find their own way. They milk goats, plow potatoes with horses and butcher cows. The kids know where their food comes from.
Also, lots of cooking, plays, festivals, arts & crafts, small engine repair for the older kids, knitting & sewing and kids are allowed to "target practice / hunt for food" with sticks in the woods.
Basically pretty well rounded. I was the baker for awhile as a volunteer, and I will never forget the story one of my daughter's classmates told at lunch about her pet rabbit. It had done some damage to the house a few times, then she said "we had naughty rabbit stew for dinner..."
However, all that said, we have been home schooling since Covid.
I would have loved to go to this school as a kid though.
