I’m installing James Hardie “HardieShingle” panels that are 16″x48″ and need to do some cuts around windows.
A jigsaw seems best suited for this task, but what type of blade should I use (regular wood or metal-cutting blades dull quickly)?

The Titan Impact X 440 offers great coverage with minimal overspray.

You can buy a carbide grit blade in HD and Lowes. Sometimes you find it in the floor tile area.

They exist, the carbide teeth on the blades are tiny and hard to see, but the pacakge should say something like "fiberglass, cement board, and brick" (who's cutting brick with a jigaW??)

If you have trouble locating some in the supply houses or HD/Lowes, Dewalt has a factory service center in Westwood off Rt 128 and Bosch has one down in that area too. They both stock a lot of the accessories, blades, etc. for their tools. Call ahead first but they should have them in stock. I know bosch makes a grit blade for cast iron that would work on the FC for a recip, I would assume they would have the same set up available for the jig saws.
I've never used a jig saw on FC, I always assumed the dust would be terrible. I have the FC shears, and use them whenever possible. The times when I cannot use the shears, I use one of the cheap masonry blades for a circular saw and do the clean up in the corners with a utility knife or one of those little hand saws that use recip blades (use the fine tooth blades). The cheap hilti masonry blades for a circ are $2 or $3, the dust between each (jig vs circ) is probably similar but I think the circ's cut would be much better and much faster. The circ cuts very clean, almost sands as it cuts whereas I would think the jig saws cut would be much rougher.
Actually the dust is limited to a little bit on top of the cut,much less than a saw blade and it does not blow around like a skilsaw cut.
