I am building a level 2 character for D&D 5e.
For story reasons (I just had to break ties with my patron, in a very fun way), I can no longer be a warlock.
Is there a class (Unearthed Arcana is allowed) that will allow me to basically use the Hexblade warlock's Hex Warrior feature with a weapon (XGtE, p. 55)? Specifically, this benefit of the feature:
When you attack with that weapon, you can use your Charisma modifier, instead of Strength or Dexterity, for the attack and damage rolls.
My goal is to dip a max of 3 levels in a class other than bard. But a pure bard build is preferable!
I can also use anything in the official rule-books such as Xanathar's Guide to Everything, and Volo's Guide to Monsters.
I also saw many people say that "That's not how pacts work" and while you are technically correct, this was a ruling from my DM for story reasons, not from us misinterpreting the rules.
Imagine a reincarnation where the character stays exactly the same, but I need to switch classes.

One niche method of doing this is the shillelagh cantrip
The shillelagh spell states:
One way to acquire this spell is the Bard's Magical Secrets feature which states:
Because shillelagh would count as a Bard spell, it would allow you to use Charisma (your spellcasting ability) for attacks and damage.
Another similar method, pointed out by user @Ruse in a comment, is the Pact of the Tome for a Warlock - it lets you treat the cantrips you choose to learn as Warlock spells, and thus they would use Charisma as well.
Note any other methods that allow shillelagh to count as a Bard, Warlock, or Sorcerer spell will also accomplish this. Overall, this is a rather small use-case, as it only applies to clubs and quarterstaves, but it is better than nothing.
Besides features like the above, the cantrip is only available to the Druid, the Nature Cleric, and the Unearthed Arcana Giant Soul Sorcerer (specifically the Hill Giant subclass). Of these the only one that has Charisma as its spellcasting ability is the UA Sorcerer subclass. You could take this class/subclass, and it would require at least one level into Sorcerer.
