Zoro>Fujitora>Sabo>Law~Luffy is the pecking order of the Birdcage top dogs which is quite a force. 2 top tiers, one Yc1 and 2 Yc2s.
Among Beast Pirates, there are 2 critical obstacles - King and Kaido, the rest is fodder.
Law should be used against that fodder as that is where he is the most effective in this battle. Switching the souls alone of Queen, Jack, Flying Six will render them nearly useless, then detaching them into pieces will seal the deal.
That leaves Luffy, Fujitora, Sabo and Zoro to deal with with 2 critical obstacles. While Luffy is not much help as he is known one-shot material for either King or Kaido, in team he could still be used for distractions if nothing else.
Sabo should be incredible CQC fighter but his style is incredibly ineffective against both obstacles. That makes 2 useless guys in Birdcage team, it is all up to the two swordsmen.
Using Zoro and Fujitora to take care of King would be bad strategy, while they can keep him in check, all their efforts might result in nothing as long as King remains in flame mode.
That means the two ineffective ones, Luffy and Sabo, should be deployed to keep King in check. Hopefully, Sabo's observation, reflexes and haki are good enough to protect Luffy from Jackpot.
Zoro and Fujitora team up against Kaido and win, then they proceed to go down the ladder and eliminate King as well and ultimately achieve victory.
