First, I think you need to decide if you prefer to navigate in the default Page mode (single button access to 4 sounds) or the Numeric Pad mode (two-button access to 16 sounds). That will probably have an impact on how you want to organize your sounds.
But either way, I don't think you'd typically want, for example, all your APs together.
...In Page mode, I think it would be better to have the four buttons recall four sounds you're likely to switch between in a song (say, a piano, an organ, an EP, strings) rather than four different pianos as ou would if you had grouped all your APs together. BUT... you might then want all your pianos to end up under position 1, all your organs under position 2, all your EPs under position 3, and all your synth sounds under position 4, or something like that. So you'd still have one way to remember where to find sound... and even if you're in the wrong bank, button 1 will probably get you SOME piano, even if it's not the one you preferred.
...In Numeric mode, with quick access to 16 sounds, you probably don't want 8 pianos and 8 organs or anything like that... you probably want more variety. Which again argues against putting all your APs together.
But in the end, patch selection remains a Nord weakness. In this respect, the best Electro was the 2 which had 8 select buttons instead of 4. At some point, you'll probably want to use a smartphone app for patch recall.
