I am cutting simple marquetry pieces with a jigsaw using the sandwich method and a 6/0 blade, the finest cut, on my Hegner saw. The problem is the saw leaves a rather wide kerf, maybe 1/64″. I’ve been trying to hide it by rubbing appropriate colored fine sawdust into the gaps between the pieces before I veneer glue. But you can still see the kerf line if you look closely. What I’m wondering is this a limitation of the jigsaw method and to get really professional looking results do you have to go to a hand saw veneering donkey?

I DO NOT do marquetry .
But what you posted made me thing of cutting the problem 'hunks' a bit higher than the others and sand off to top!
Cut at 7-15 degrees depending on thickness of the veneers.
If your stacking multiples you have to cut at 90*.The bevel method will take care of the kerf I use a 2/0 blade most of the time.
I saw mostly by hand, its similar to therapy.Ron in Peabody
I've used a similar technique to what you describe very successfully. There are many methods to do marquetry, one of which is to create packets or a sandwich of different colored veneers under a pattern with the background at the bottom. With the saw blade at 90 degrees you will be left with a small kerf, however, that kerf will for all intents and purposes disappear when you glue your project. I use a urea formeldehyde glue that has a dark tint to it and a tiny amount of the glue will work its way into the joint. If you use white glue, the moisture in the glue will cause the fibers to swell slightly causing the gap to close.
I suggest you do a bit of experimenting with some scraps and glue a simple project to a substrate then see what you have. If you still have an unacceptable gap, another option is to seal the wood with a think coat of shellac then apply a wood filler. You can also tint wood fillers if you think it necessary.

Look up and try the Double Bevel method. I do all of my marquetry on my scroll saw using this method. The double bevel technique eliminates any gaps due to the blade kerf.
