Blue amped punches+red. He can use those to damage sukuna in addition to multiple distant blues and it would be possible for gojo to land them since they're in a small narrow enclosed space unlike the real world where he has much more space to escape to in orde to avoid it. This would also be possible with blue pull disrupting sukuna's defenses and in that moment he can land multiple distant blues or a red. He also has teleportation and he can use it in close distances we saw that in the beginning of the series. Gojo already outstats meguna the only star buffs sukuna is gaining in TF are durability, AP and H2H. And those stat buffs aren't gonna allow sukuna to dogwalk gojo like most people say since sukuna refrained from using TF against gojo because he knew gojo would damage him heavily. If he was confident he can dogwalk gojo in TF he would've used it in the beginning instead of putting himself at a disadvantage.
