I know what you're looking for and afaik it does not exist as a current game setting.
For all fights (except 1, stupid cyclops in Vale) I use standard mode.
I use the right mouse button to control my camera while I move (and move relative to camera facing, rather than camera track to moving), I will use WASD for movement which I can get with 1 finger, and still reach for 1/2/3/4. If you're not used to doing something like this it WILL confuse your fingers and you have to be quick to reset your hand(s) when you're done so you can reach all your actions or you'll be hitting the wrong things for a bit.

*most* of my actions are on 1/2/3/4, CTRL 1/2/3/4, ALT 1/2/3/4 or CTRL+ALT 1/2/3/4. I use my oGCD actions with mouse click.
hotbar 1/2/3 (class actions), hotbar 10 (runs beside the party list for targeted macros)
hotbar 4 -shared chocobo/mount actions, UI add/remove macro
hotbar 5/6 -shared class change & "swap" macro, they overlap so only 1 is visible and I click to toggle them
hotbar 7/8 -shared Marking/targeting & emote/levequest again with a toggle macro
hotbar 9 - shared food and potions
