The cabana bar at Swan and Dolphin used to always have the Sunday ticket. Haven't been there on an NFL weekend since COVID, so can't confirm this year, but a good choice if they still have it. They only have four TVs - so you still had to get there a bit early and make nice with the bartenders to ensure you got the game you wanted.
'Phins at Dolphin has a great TV set up - no idea if they have Sunday ticket, but if they do that would also be a good on property spot.
ETA: I just checked DirectTv's Sports Bar Finder app and Cabana bar shows up for having Sunday ticket, Phins does not. May not be 100% accurate, but probably right. Also shows Splitsville, AMC Dine In, and Boathouse in Disney Springs. And shows "Springs Food Service" with the address of Coronado Springs Resort - wondering if that means Rix has it?
