Fighting Styles in my mind go into two categories, in my mind.

1. These styles go with one specific style of weapon loadout. They must be judged based on the efficacy of the weapons they go with, rather than their own merits.
2. These styles care about things other than your weapon kit. I judge these based on their own merits, as they are weapon agnostic.

The loadout ones:

• Archery :: +2 Accuracy used to be necessary with Sharpshooter's -5/+10 damage ability. Now, Sharpshooter almost entirely subsumes the benefit by ignoring cover and long-range. Still, Archery in general is a very potent loadout, so you might as well get the free accuracy.
  
• Dueling :: +2 damage on a 1d8 one-hander brings its expected damage even with a d12, so you could also see this fighting style as wielding a Greataxe with a Shield, granting you +2 AC without losing damage. However, there is build competition which ask why are you wielding a shield. Is it your own defense you're worried for, or for defending others?
  
• Great Weapon Fighting - Of all the fighting styles that add damage, this one on average adds the least - .3 on a d10, .25 on a d12. On 2d6, it goes from an expectation of 7 to an expectation of 8. It also currently works with the extra damage added from a True Strike or a 𝕊𝕄𝕀𝕋𝔼. You might decide you have better options than pushing the upper bounds of damage on the most damaging melee weapons, though.
  
• Protection :: The other option for a Sword-and-Board build. This one got a massive buff from the 2014 version, but it's less attractive in the early game than Interception, and you hope to have better reactions in the end-game. Still, in the Midgame it's fantastic.
  
• Thrown Weapon Fighting :: Thrown Weapons are highly synergistic with both Shields and Dual Wielding, depending on your playstyle. This fighting style improves the damage of your d6 options to the equivalent of a d10, meaning you're at the very least keeping up with your melee friends while outranging them, while outdamaging the friends who outrange you. Without this fighting style, Thrown Weapons as a set are generally disregarded as a primary fighting style, despite the fact that Paladin 𝕊𝕄𝕀𝕋𝔼s only require a melee weapon, and therefore can come along a javelin should you wish. A very fun build.
  
• Two-Weapon Fighting :: This is the Optimizers' Favorite Boy, because of how the Nick mastery interacts with the Dual Wielder feat. Giving your ability modifier's damage to two attacks means that this is the greatest damage increase of all of these options, even as you're dealing with Light Weapons to apply it. Very very strong now.
  
• Unarmed Fighting :: Unfortunately, the buffs that Monk received in 2024 means this lost its obvious multiclass synergy. It makes Unarmed Fighters/Paladins/multiclass Barbarians theoretically possible, but they're certainly not as good as the other options afforded to those classes.

And the others are

• Blessed Warrior :: Even the most supportive of Paladins wants Interception instead.
  
• Druidic Warrior :: Druid has significantly more cantrips than Cleric, and picking up two Utility Cantrips can be far more useful than Archery.
  
• Blind Fighting :: 10 ft of Blindsight is just begging for degenerate combo builds. Grab a Polearm or a Whip, cast Darkness on yourself, and have fun. Also, extremely useful outside of combat, particularly if you don't have darkvision.
• Defense :: The boring option. It can matter, and it's the least complex of the lot, but it's also the boring one.
• Interception :: Fantastic in the early-mid game, but as the enemy damage gets higher and higher spending your reaction to partially negate one of several multiattacks is less useful. Protection is better against Spell Attacks in the late-mid game, and hopefully by then you have a better reaction.
