Generally speaking, what comes out of the camera live should have nothing to do with the internal recording codec, but check the specs of what the camera is spitting out of the SDI(or HDMI).
You might want to talk to Sony to get the exact specs of the output of that camera, I don't see it listed anywhere. There are no hard and fast rules about a camera's internal codecs, bit rate and color space versus video outs, they all seem different. FWIW, I shoot a lot of green screen. Totally possible to shoot decent looking green screen with a 4:2:0 8-bit output but you have to nail the green screen, subject lighting, contrast, WB, green screen illum ratio versus subject, etc. And even when you do, you will not have fine control and latitude over spill suppression, relighting, and pushing keys. 4:2:2 and 10-bit are much better for all of that and 4:4:4 and or uncompressed even better. Who is your audience and how visually sophisticated is the project? Do the keys need to look perfect or just good enough? How good are you and or your gaffer at lighting green screen? Are you going for photorealistic to try to make your keys appear real? Will the BGs be plates shot with? Stock footage? Stills? Motion graphics? Virtual sets? You're dealing with a style of shooting that has a lot of variables and can be shot and composited in a lot of different styles.
If image quality is important, you should consider using a better camera, a sub $3k Sony isn't bad and may be good enough for your needs but it may not give you an optimal image, depending on what you are trying to achieve and how picky you and or your clients are.
The bit only affects the tonality of the colors. Mostly something you's notice in the gradation from light to dark or a blue sky from deep blue to light blue.
So it could affect the look of you talent and grading options, but shouldnt affect your greenscreen too much
