I must admit I got lost off with the GOOD and the BAD, however
When posting screenshots of issues include the tool options and layers in the images. So many things in your work flow affect the result. Crop with allow growing on or off. Crop with delete cropped pixels on or off. Canvas size with width / height linked not linked. Size of the layers (obviously different as shot 1 & 2 are single layer 3 & 4 are two layers)
I can get #4 easily with the Image -> Canvas size by adding to the initial values or multiplying factor to the initial values depending on what I want. Uniform size border or retain aspect ratio.
