Alright /p/ time to help me pick out my next camera. (B4 sell your gear and get "_brand_")

Been photographing for 10 years now, and 5 years getting actually paid for it! I'm gaining steam but have limited funds on my next upgrade. I don't do sports and have done two weddings, gobs of portraitures/ headshots, an engagement shoot, tons of product shots (mostly restaurants). Given that is still going to be my subject(s), what do you recommend?

I'll add further factors by saying I'm a Canon shooter and have a 5D mk II and lenses including, EF 50mm f/1.4, 100mm Macro f/2.8, 17-40mm f/4, 70-200mm f/4, and 24-105mm f/4...So I have invested some money into glass covering that brand. Canon is the first go-to with only a max of $1000, what route should I take. Also, I'm aware Sony can also be an option, but I'm worried about the battery life, the compatibility, and the Fotodiox adapter hunting in AF.

I know there's a lot to unpack here but I just want to make a good decision that will last for a projected 4/5 years of use. Any help would be appreciated, and thanks in advance for any help or leads. Be back in a few hours to check recommendations, if any.
