With the fall of Big Mom, I think there are two candidates who will eventually replace her, well technically 3... but.... I don't see 1 of the three even being relevant with how much Oda has neglected her. So we'll stick to the two relevant ones.
1st. Yamato, at the age of 28. Still a solid decade away from entering the "prime ages" of 40s. With plenty of potential to grow with her insane natural body and haki potential. I think he's the clear opponent for Blackbeard's female pirate, Catarina Devon. With it being the clash of mythological DFs. Yamato will also serve as the "Oden" equivalent, joining up with Luffy right before the clash against Blackbeard (hence we're seeing her whole "oden" journey happen in the cover story).
2nd. Boa Hancock, at the age of 31. Still a decade away from entering the "prime ages" of 40s. Her DF has insane potential without even being awakened. She's a confirmed CoC user of an island that's hyped for it's haki, yet Oda has chosen to keep her haki hidden for now. Thus we don't know her full capabilities as a fighter at all. Ironically, Yamato the newer character has displayed more of her prowess than Boa Hancock has.
So the inevitable clash to be the top female pirate on the seas is between these two. Who will be the strongest at their peak? In my opinion, it'll be Boa Hancock.
