It seems we a re like peas in a pod Tom,
Even my trusty 5D which I have had since its release has only ever been set to RAW, M, and manual Kš. I only use the centre AF point. Menus may be important to some, but not me. And as you say, the ability to see the world largely in terms of a single field of view is indeed liberating.
Comforting to know I am not alone.
