What level of exploration capacity does the C8X have? Should we expect it to be on par at finding things with the Origin 315p, or is it mostly for very short-range use? Is the exploration capacity the same between the two variants?

The Pisces is designed for much shorter duration expeditions than the 315p due to the lack of onboard facilities, such as a bed and toilet. Historically, it operated out of the Carrack, so had no need for these as the crew would return to the mothership. The exploration capability between the C8 Pisces and C8X Pisces Expedition is identical.
