I am such a sucker for goops and glops. I have shelves groaning under their weight in my quest for "one thing that does all". But as you say, they all have specific application. It's not unusual for me to use several different lubes on one gun in various locations.
So where do you get G-96?
One thing that I hesitate about using a silicone bearing product is silicone's propensity to get where you don't want it and being very persistent (and invisible) in removal.
I wonder how good of a rust inhibitor/lube 75W-90 synthetic gear lube would be? It works well on a motorcycle chain, certainly a harsh, dynamic environment.
The problem with EP lubes is you pay for something you never use, the EP additives. Technically I suppose the EPs might help the sear nose/tumbler notch friction since they are designed to "kick in" where metal rubs together (ring and pinions in a differential) but they also require heat to fully activate IIRC.
G-96 is sometimes hard to find, I bought 24 big aerosol cans wholesale a couple of years before I gave up my FFL and find my supply is running low again. But bigger sporting good stores often carry it.
As with many things there are claims on the label that it might not live up to, like removing metal fouling. Lead or copper fouling usually takes a dedicated formula to remove. Hoppe's 9, Sweets or some such. But aside from that its a pretty good product that will protect surfaces from finger printing etc with no really noticeable layer of oil.
On a gun silicone is not a problem unless you soak it into the wood, but any petroleum product is bad for wood as well.
