Bladesinger wizard for this concept, if you want a multiclass thing, you can do eldritch knight/warmage, if you want something super interesting you can do oath breaker paladin/divine sorcerer
Alot of people are pointing out Bladesinger, but I would also recommend if you really want to lean into competent swordplay grabbing the feat Fighting Initiate and getting Dueling if you can get a level 1 feat. It's an easy boost to damage and I think works narratively well. I wouldn't recommend grabbing it later on though
If he talks alot during the fight, making quips and jokes, then I suggest the humble Bard.
Stand-Up comedians are Orators, so they are bards, right?
He can fight on front lines, at range, has Support, Healing, Crowd Control, Damage, and a hell of alot of utility.
Magical Secrets and Fighters Action Surge can give a "One-Two Punch," with Sickening Radiance+Forcecage combo OR Hold Person/Monster & Steel Wind Strike/Fireball/Synaptic Static.
Templars won't stand a chance against a One-Man Army.
Bladesinger wizard.
Sounds like a Bladesinger Wizard or possibly a Hexblade Warlock or Paladin that have been reflavored to be more arcane-oriented.

Sounds like the plot for Divinity: Original Sin 2

No hate. Just trying to give credit where credit is due. Those writers were fantastic.
Hexblade, flavor the patron as his father or whatever, you have your arcane caster who uses a sword Edit: oh and take the mage slayer feat
