A few quibbles about using SFO gateway:

- CX uses the dreaded 74B which means:
a. No audio/video on demand. Some planes even use obsoleted 8mm video tapes for "on-demand" movies. Jittery video, muffled audio, poor selections.
b. No in-seat power supply (Empower).

- CX FC lounge at SFO is just a tiny little room to the side of the BC lounge. Wins my "CX's Worst Lounge in a Major City" award. Drinks selection: so-so. Food selections: next to nothing. If you have a long layover, spend the time elsewhere.

My other quibbles on CX's FC product are systemic (i.e. affects all FC) such as an unbelievably bad headphones (see separate thread). But that's another story.

Aside from those minor nitpicks, I'm pretty sure you'll enjoy CX F class from any gateway.
