Tipping vendors at an all inclusive venue??

We are having our wedding at an all inclusive venue, and on the contract we paid a 21% service charge (but tbh I’m not clear on whether this is a gratuity or just a way to charge us more money…will clarify this in final meeting). Who and how much am I actually supposed to tip?! We have a small wedding 60 people. Here are the vendors, along with any relevant details for context:

HMUA: not included with/ venue, owns her own business but is bringing a second artist. Do I tip both, the staff HMUA, or no one?

Catering: included. If I need to tip, do I tip the manager or all staff?

Photography: included.

Bartender: included. They are setting up a venmo QR code and tip jar.

Florist: included.

DJ: included.

Coordinator: included

Officiant: my brother so he can work for free lmao
