As for level split, the usual route is start Paladin 1 or 2 (to get Heavy Armor and potentially Smite online ASAP), then take Hexblade to start using CHA to attack and grab Eldritch Blast for a ranged option, then back to Paladin until Level 6 (or 7 depending on oath) to get Extra Attack and Aura of Protection (and potentially a beneficial Paladin 7 oath ability). From Hexblade 1/Paladin 6 or 7, decide if you want to continue on as mostly Paladin with just a Hexablde dip, or continue as a Hexblade Warlock from there.
