At one time I had a Top Secret/Siop/ESI clearance. It involved my access to nuclear targeting data, nuclear inventory on ships or on land and DefCon info as to locations that would activate. I did not have access to technical data related to equipment design or capability. I think it silly to think Trump would have requested weapon schematics...Yes, I think they are quite likely design schematics. A judge isn’t gonna issue a warrant for a former president for information that is generally available and of no national security interest even if technically classified.
He would have had access to inventories, especially related to navy ships at sea...he'd need to know if he wanted to order a limited strike on North Korea or for retaliation against a limited Russian strike in Europe...
