This is so interesting and had made me reflect on my team (3 professional women, 2 professional men, 2 men in secretarial roles).
If I am being formal. I address them as "team". On an informal side bar on Teams, i often say "chaps". I do , however, appreciate that term is gendered. I would stop it if a female member of staff objected.
In an all female team in my last job our (older, female) manager called us "girls or ladies", and I didn't mind that at all. Mostly because l liked being in an all female team.
If I'm very close to a male or female colleague I might address him /her as Mr X or Ms Y. But that is a tongue in cheek joke.
Surrey OP, I know you have been eaten for breakfast on the term "girl boss" ( and I hate that term). But really what it making sure they understand the project, leave them to do it and be there if they need a hand.
Trust them, don't micromanage

"Grow them so they can leave, nurture then so they don't want to".
Ok, slightly sickly. But ultimately true.
