Don't overthink it. Pretty much any modern hollowpoint at a reasonable velocity is going to expand reliably.

The one-shot stop is a myth, you're very likely going to have to put multiple rounds on target anyway.

Just choose a round that law enforcement agencies have had good results with and that feeds reliably in your pistol. Better yet, find a handful of different ones in case your preferred choice is not available.
