As of my last update in early 2023, the BET Awards 2024 have not yet occurred, so I cannot provide the winner for the Best Female Artist category for that year. The BET Awards typically take place annually in June, and the winners are announced during the live ceremony. To find out who won the Best Female Artist award for the BET Awards 2024, you would need to check the latest news or the official BET Awards website after the event has happened.
