This is terrible but you shouldn’t care so much about your spilt as what matters is how hard u train and how much u eat. But if you really want the optimal spilt I find Arnold works the best ( arms and shoulders , legs and core , chest and back, rest repeat.) this can be thrown in any order and you should place your accessories (forearms etc) at the end of your shortest days

1)push 2)pull

in what world are bicep exercises considered a pushing movement and in what world are tricep exercises considered a pulling movement
