8 ball pattern play should be fairly simple, in theory, not the actual table layouts you get in a game that are random and never ending.
Look at the clusters, look at the 8 ball, see what has less issues and just play backwards from the 8 and a few key balls as to where to start. The pattern play just comes into play from those basic few things, keeping away from going into balls if possible, keeping the shots as short as you can (no moving around table end to table end), don't pass up shooting a ball if it may be harder to get back to it later, picking the balls that will lead to an easy 8 ball at the end. I think just those 6 or so basic ideas can form the basis of any pattern play, they dictate what to shoot based on the bad things that can happen if you play the other shot.
I have always used the general good things to do vs memorizing positions of the balls to plan and play the shots and just apply the basic theories to whatever the layout happens to be. I also use Buddy's famous "don't play position if you got it" saying, it's in my head whenever I see a shot I can shoot that may be a little bit tougher than another one, but if I save it for later it can be even harder or impossible from some other angle. Better to shoot a 85% shot you are lined up for than wait to get it to a 95% shot but only have a 30% chance of getting to that better position later, if that makes sense hehe.
Actual set up patterns would just give examples of the dangers to avoid or how to deal with them, but the basic few theory ideas just need to be there to apply them in any situation. If you know clusters are bad and you don't want to leave the hard shots till last, that is true in just about any game layout (with exceptions when you need to play safe and use those clusters for that). Most games for non-pros also change sometimes shot to shot when someone plays bad position on a ball.
