You have tab targetting in the from of hold r2 and then hit l1 to cycle.

You can also cycle party members via up/down on dpad - you need to confirm your selection by hitting X else it works like mouse over... it will only cast that one spell on the person then switch back it whatever party memeber you had targeted.

You can cycle via enmity list by holding l1 and using up/down on dpad - again X to confirm.

There's also target filtering that will work with just left/right on the dpad but you need to configure that how you want it to be like in character settings I believe. Then you switch to those filters using I believe r1+face buttons then you can cycle through those targets using left/right on dpad.

Think that about covers all the possible targeting options for controller users.
