Lens for wedding photography

Super excited that I’ve booked some weddings this summer, and I’d like to purchase a new lens.

I have a canon 6d mark ii and the following lenses:

EF 24-105mm kit lens Canon 50mm 1.8 Tamron 35mm

Heard the Canon RF 28-70mm F2 L or Tamron 35-150 f2-2.8 are good options but open to other suggestions and input. Thanks!
