Glass - (Depending on use), we go with our "regular" clear from General Formulations.
Drywall - We used Oracal 3628 on an interior install last year and it fell off the wall. Never saw the wall myself (I'm the inside graphics guy, not the installer), so no clue what kind of shape it was in.
Textured Drywall - We used Arlon DPF 8000. It worked great in the field, but there's no way I'd recommend it. We tried three different rolls from two different suppliers, and all three had adhesive residue on the face of the material. When we rejected the first two, Arlon's response was "just wipe it off". (Which reminded me of Avery's attitude in the late 90s-early 2000's when they had the same problem- and which caused me to stop using their product unless it was specifically requested). Our "regular" digital supplier suggested Sihl's new 3220/3221, but we haven't tried it yet.
Wood - If it primed, we use our standard decal material from General Formulations.
Vehicle - I prefer 3M IJ180, and we've had success with Oracal 3751.
Painted Concrete - Our most recent install on a painted cinder block wall was the Arlon DPF8000.
Floor - Haven't done one in more than two years. I don't remember!
