Non-native as well but for me, “female” is an adjective and only used as a noun in technical setting. If used in regular conversation setting, it’s condescending and dehumanizing.

Good:

• There are fifteen females in the survey.
• The female is more aggressive, typical of hyenas.
• You bought the wrong USB cable, this one is a female.

Bad:

• This female is not very good at her job.
• You females need to tone it down.
