Interesting discussion, I use hold down clamps for the material, the only time I have used contact cement or double sided tape had to with cutouts within the clamped border. Double sided tape in most varieties adds thickness to the project. Wide masking tape and contact cement works well but it needs to be lined up perfect before pressing the piece down, you miss you will need to pull the entire piece up.
My solution is only tape & Contact cement within the cutout, tape, contact cement, reversed tape (sticky side out) tape, very little contact cement is needed. Clamp a guide horizontal to get that reference for zeroing the X Axis, press the work piece down with the glued tape between for the cutout, clamp the perimeter, but remember to get that one axis dead on.
I do not rely on my spoil board grooves for my horizontal X Axis reference. I lower a bit, go from bottom left, clamp, jog to bottom right and double check about 3 times. Easy if you have yours screwed down and leave it.
Then just place your work piece against the guide, watch out for the tape so it doesn’t touch, align it, then lower and press down.
Zero your project from your design zero, I prefer center zero.
If you allow a tad bit excess in your material you will be perfect.
