So, I think I have settled in on an approach for shielding. I plan to apply 3 layers.

1. Copper Foil Tape as a base
2. Kapton Insulating Tape in between layers as an insulator
3. Silver Infused EMI Fabric as the top layer

The lid and the deck will be separate so my goal is to bond them electrically. I am going to do some controlled testing of soldering directly to the EMI cloth. Otherwise I might use some kind of alligator clip connecting the two.

The copper tape is self adhering and the adhesive is conductive so I'll run some tests but I plan to do a 50% overlap when applying the strips to get good coverage but also a good electrical bonding.

The Kapton tape is also self adhering so I'll apply that directly onto the copper foil tape to provide an insulated barrier on top of the copper foil.

The EMI fabric is a bit more of a challenge but my thought is to spray with adhesive and then lay it into place and fit the fabric to the inner contours.  I plan to do some testing but I am hoping I can solder a bond between separate pieces.

I might also add a grounding terminal to the deck to ground the shielding to whatever ground is available.
