Level 4: A Wisdom/Charisma oriented Fighter

Hi! This is going to be a short one as the idea is for it to be versatile. Maybe you want to make a very wise or charismatic Fighter for Roleplaying reasons. So I'll give you ideas that can help you do exactly that while being a powerful entity in battle.

Stats
We are skipping the race section and we will asume we don't have racial modifiers. We are also going to use the standard array for this.

First of all, wisdom and charisma will not affect your AC. Depending on what you want to do you may need a strength of 13 to use chain mail armor (16 AC) or you may want to pump up your dexterity. In order to fight constitution is always useful because of the extra hitpoints.

Lets do an example, lets say that our fighter is an experienced and very wise warrior. When they were younger they excelled in melee combat and resistance. Now their body isn't what it was, but they remain strong as a warrior:

Str	Dex	Con	Int	Wis	Cha
13	8	14	10	15	12

These stats will give them the ability to use chainmail and a moderate boost in hit points.

How do they attack

Its true that this fighter in level 1 will not be able to attack. That's the reason this build is for level 4. In level 4 our fighter will take the Magic Initiate Feat.

Magic Initiate

Choose a class: bard, cleric, druid, sorcerer, warlock, or wizard. You learn two cantrips of your choice from that class's spell list. In addition, choose one 1st-level spell to learn from that same list. Using this feat, you can cast the spell once at its lowest level, and you must finish a long rest before you can cast it in this way again.

Your spellcasting ability for these spells depends on the class you chose: Charisma for bard, sorcerer, or warlock; Wisdom for cleric or druid; or Intelligence for wizard.

 This feat is the essence of this build. For our example we will take druid as there are two cantrips that mix very well with this build of the fighter: Shillelagh and Magic Stone.
Both of these cantrips can take advantage of the fighter's Extra Attack feature and some of the class' traits.

For magic stone the Archery Fighting Style increases the damage while using a sling (however weapon bonuses do not apply). For shillelagh the weapon bonuses and class traits work as normal.

For a charisma oriented fighter we would take magic stone as the warlock class. Using this build its better to go a range fighter rather than a melee fighter. This is because without multiclassing and taking the hexblade warlock patron we can't use charisma for our attack and damage rolls.

Compatible Subclasses
Now lets talk how the fighter subclasses work with this build.

Arcane Archer and Eldritch Knight: These subclasses require intelligence, if you want to subclass for one of these and be effective in combat you would have to nerf your defenses in some way.

Banneret: The effectiveness of the traits of this subclass do not differ by comparing them to a regular fighter build.

Battle Master: The Rally Maneuver is better when choosing a charisma oriented fighter as it relies on your charisma modifier. The maneuvers that do not require saving throws will work as normal, the others will be worse as they depend on the character's strength and dexterity.

Cavalier: May of this class features depend on strength and constitution modifiers. Which our build do not excel in.

Champion: Many of the features in this subclass are very useful. Easier crits, bonus to physical saving throws, etc. If you have less than a 10 in strength your long jumps will be nerfed in level 7.

Samurai: This subclass works very well with the wisdom variant of our build. All abilities are not nerfed in any way for having low strength or dexterity. And the social interaction feature is boosted by having a high wisdom.
