John, where do you live?
Find an airport that rents taildraggers, preferably a Cub, and get a
couple of hours dual with you flying from the back seat.
I promise you, you will learn to use your peripheral vision and keep the
nose up to land.

OK, I'll bite. Why is this skill so much more important in the Cub, so much
so that he will learn this skill, only in a Cub? (or so implied)

Jim, have you ever flown from the back seat of a Cub and done full stall
landings? The Cub nose stands pretty tall.
Even in the backseat of a Champ, I can still see forward pretty well.
