The radiotap fields are defined at https://www.radiotap.org/fields/defined. As part of the radiotap header, there is a Present flags field which indicates the specific fields that are populated by the device and driver. Different devices populate / pass up to user space different items, sometimes depending on the type of frame received. If you don't see what you are looking for, I would say that the adapter and driver you are using is not providing it, so nothing Wireshark could do. Try a different adapter until you (hopefully) find the fields you are looking for.
I do not see any SSI values in the Radiotap headers
I assume you are referring to signal strength indicator(?) - if so, wouldn't the antenna signal fields in your screenshot show this?
