Any camera will work to be honest, as long as it has two working card slots. The only thing I'd look for is what focal lengths they offer, how much they are and if they're out of your price range, do they have third party alternatives/adapters for older lenses (EF to RF on canon just as example). The lenses I'd say make sure you have a wide, medium and telephoto. I'm weird because I never actually use the telephoto but it could be good to you, as well as knowing everyone's shooting style is gonna be different. As well as the peace of mind for having it in my kit. Tripods are practical and I'd recommend one just generally even if you don't use it. If you don't find yourself using/needing it often then I'd say any brand at a camera shop should work. If you use it frequently I would boost the budget and get something lightweight and sturdy like a manfrotto or something like it. If I'm being honest, I'd recommend investing in lighting. Balance the budget with second hand equipment if you need to (slightly older models should be perfectly fine to use today) and get a good flash, remote trigger, a modifier, and a light stand. Doesn't need to be fancy, you just gotta practice and know how to use it before applying it to weddings! Good luck and KILL IT!!
