The practise run for this went great, then the recording took about two hours as I kept making mistakes!
Gladio is keeping you alive, he will soak up all damage and prevent Ardyn from killing you and Golbez and from paralyzing you. His counter will also come in handy of course.
Vayne is here for the big damage. Use the first FR to cancel there FR, give yourself time to drop your Leo and Seymour calls, they do make all the difference. Ardyn likely won't be dead after your BT phase but jump into summon phase and finish him off.
It then becomes a one sided fight against Golbez, Vayne's free turns will keep the turn count down and your second FR phase should be followed by Skill 2 into LD to keep a flow of attacks from Vayne going.
Yang is here for off turn damage, its consistent and lasts a while with his recent reworks.
