HarshalShirsath I'm in a similar boat to you. I'm currently considering OAK-D-SR-POE as an option. It has the closer stereo depth of the standard SR, but with an additional TOF sensor and IR sensor. Allegedly, they are planning on adding alignment of the TOF to the stereo but even without that the IR+Stereo should give much better depth results than the standard SR or Pro series at close ranges.
I'm still a month or two out from making final purchases for my project, so if you find something that works for you for these close ranges please let me know! If I end up purchasing the SR-POE cameras and no one else has notated it I'll try to post the accuracy numbers at close range
