Here is a simple SCH setup for controller that uses the least amount of buttons and has easy access to critical functions.

First lets set up some macros:

(SwiftAscend)
/micon "Swiftcast"
/ac "Swiftcast"
/ac "Ascend" <t>

Now go to Character Config> Hotbars> Cross> General and uncheck "Use pethotbar".

Then go to "Set Selection". Uncheck "Auto swift when weapon sheathed/unsheathed".
Then check "Enable customization when weapon is sheathed" and make sure Hotbar 1 and 3 are checked.
After, check "Enable customization when weapon is drawn" and make sure hotbar 1 and 3 are checked.
Now tapping R1 switches between hotbar 1 and 3 and skips the premade pet hotbar!

Next go to Character config> Hotbars> Cross> "Enable expanded controls" and set the (R2+L2) and (L2+R2) both to cross hotbar 2 left

Finally the actual layout, I personally use a Dualshock 4, so your mileage may vary:
