Hello Ocporbust,
being a fiber based link it should be 1000 Mbps full always not configurable.
I don't understand why one side was telling it was half duplex.
I would try to remove all duplex commands but I suspect the gbic is not working well.
Edit:
being a GE port with two possible plugs
int gi0/3
no full duplex
media-type sfp
shut
no shut
Hope to help
