For the red/black, the 140 seems like a good choice for lid mount. It’s got enough extra room to allow some flexibility.
For the red/black 700mm x 500mm, here are the images from 3 different cameras mounted in the lid:
160 degree:
.
140 degree:
.
and 120 degree (note this is fuzzy because I didn’t take the sticker off the lens):

The 120 cuts it pretty close, while the 160 captures too much extra around the bed.
