I was thinking using Al type anti seize, may not be a good idea on all Al parts, since it is already a case of Al on Al. That permatex is okay on steel bolts, just not sure about all aluminum.
That may not be exactly the case. I believe these are metal mixtures, and may include graphite, moly, oil, etc.
But I think your premise that the AS materials must be carefully considered is a good one.
Loctite C5-A. A Costco tire installer turned me onto this years ago and I've never looked back. It's a Cu/Al/graphite-filled grease. I use that stuff especially on bikes where a steel screw or bottom bracket shell threads into Al frames. I used to use it on spark plugs but not anymore.
I use this a lot, including wheels (on the hub, not the lugs), but decided against it after a while because Al and Cu aren’t a good pair. I read someplace that Zn anti seize is best for aluminum to steel connections, so that’s what I use there.
Aluminum to aluminum I’d probably consider nickel, marine type, or regular grease.
