Any grease will generally be better than no grease, but most of my firearms run on no grease just fine. Why not use an automotive grease if you prefer? I've never seen a grease that was so stiff that it prevented any of my firearms from functioning properly.
Weapon Shield Lithium Grease is pretty much my "go to" firearms grease now. I've tried a ton of them, along with a lot of the automotive type greases. Weapon Shield doesn't seem to attract as much crap as many of the others do. It works really well on AR-15 / AK-47 bolt lugs, and the hinge bearing surfaces on O/U shotguns.Does anyone use Weapon Shield gun grease?

Another oil good for many applications is chainsaw bar & chain oil. It's typically 70 to 90 weight gear oil with a tackifier agent to reduce sling-off and stay where it's put. A gallon costs about $13 at any hardware store.... 600 wt. oil is used in the differential and transmissions of a lot of older classic cars. It really stays where you put it. The stuff works really well in other applications as well. ...
Sta-Lube SL3151 White and Lubriplate are the best grease I have ever used on firearms.
Got this what looks like military issue rifle grease 30+ years ago at a gun show. No MIL-SPEC info on the container.
Who knows how old it was when I bought it. It's stayed the same consistancy and hasn't solidified at all since I got it. It's very thin and works very well on slide rails. Just takes a small amount, and I use a toothpick to apply a thin layer. Wish I could find more someplace.
I really like the breakfree CLP and LP products. I know they got a bad rep a few years back but ever since they returned to mil-spec they have been working very well for me. The LP is significantly tackier than the CLP.
As for grease, Jet-Lube offers a lot of different products. I would be they have a low # grease for you. I think valvoline greases are made in multiple weights, but I've never seen anything but #2 on the shelf.
