If you/your travel companion has OW elite status maybe you can kill some time over at the JAL Sakura Lounge.
CX is using the BA Terrace in SFO. The F side is only a small room inside the lounge and is nothing to write about. Compared with the AC, the BA lounge is much better.
I don't think OP can access the JL lounge based on COS. Also the JL lounge is unlikely to be open then. Even if it is open and OP can access, there is no reason to get in.
Just spend some time on the internet and have a drink or two.
