Perhaps I'm misunderstanding it, but when I looked at wide lens at BH I kept coming across ones designed for the 6300 model (I think that is the one) the one that is not full frame. What do I need to look at to ensure that the lens is designed for full frame and not the crop sensor?
There's a check box in the filter section for "Full-frame Lenses" vs. "APS-C Lenses", just check the full-frame box

I think I would want all of them to be AF...if I need to I can turn off AF and just manually focus. OR is there a reason to want some lenses to be just MF?
Main advantage to a MF lens is the manual focus will be much better/smoother/more consistent. As mentioned above most/all Sony e-mount autofocus lenses are focus-by-wire, which makes manual focusing smoothly/accurately more difficult. Cine MF lenses also have focus rings that easily fit focus pullers. If you get multiple Cine lenses from the same lineup they often have the same size and location of focus rings, so lenses can be swapped without having to redo your equipment setup each time. The balance might even be close enough to work in the gimbal without rebalancing.

What is a good wide lens with a wide aperture that is small and light weight so I can use it with a gimbal?
wide + wide aperture + small and light? You're looking for the lens unicorn; does not exist. Pick two of the three...
Just did a search on B&H; here are the lenses wider than 35mm and faster than f/2.8 (sorted by focal length)
After each lens I added AF/MF, length, and weight
Sigma 14mm f/1.8 Art (AF, 126mm, 1170g)
Venus Optics Laowa 15mm f/2 (MF, 82mm, 500g)
Sigma 20mm f/1.4 Art (AF, 130mm, 950g)
Rokinon 20mm f/1.8 (MF, 114mm, 525g)
Tokina Firin 20mm f/2 (AF, 81.5mm, 464g)
Sigma 24mm f/1.4 Art (AF, 90mm, 665g)
Rokinon 24mm f/1.4 (MF, 124mm, 590g)
Handevision IBERIT 24mm f/2.4 (MF, 68mm, 320g)
Zeiss Batis 25mm f/2 (AF, 78mm, 335g)
Zeiss Loxia 25mm f/2.4 (MF, 74.5mm, 393g)
Sony 28mm f/2.8 (AF, 60mm, 200g)
The only one I would call "small/light" is the Sony 28mm f/2.
The Batis and Tokina might be small enough also if you want AF.
For MF the Handevision and Loxia are smallest
