I admit that Lambda can be useful for some. but my brain does not think in Lambda. I always feel like I am trying to calculate the ratio of actual AFR to stoichiometric AFR on the fly. that is too much real time math for me.

You are correct that 14.7 is considered stoichiometric for true n-heptane reference. Actual gasoline is usually E10 and has approximately 14.3 equivalent. It all changes based on true composition and octane rating. And yes, the tune must be compensated to allow for that.

Everyone is welcome to change their software to represent whatever units it can be programmed to handle.
