It has been mentioned before but i want to go over it again
Conquest/hexblade

Go conquest paladin to 9 to get acces to the fear spell which in combination with the lvl 7 aura is a pretty nice combat opener and hinders enemies from sprinting into your squishy backline
For single target Wrathful smite is honestly amazing since it requires an action to roll against it
Hexblade warlock to 2 so you can ignore strength (needs to be 13 for multi) and focus on cha for spell saves, attack rolls and aura all in one
Get agonizing blast if you want to spam eldritch blast

While your control spell is going you can do the usual paladin thing and divine smite away or eldritch blast if you want to stay further away

Not saying that this is the most controlling build out there (since enemies immune to frightened exist) or the most damaging
But its one option to consider
