I have mainly only studied and done retriever training at this point as I mostly hunt duck and geese. I do enjoy the Standing Stone YT channel, and although they do cater to a variety of different types of training, they seem to cater more towards the upland sport (pointing and flushing).
Plenty of the techniques do bleed over (casting, retrieving commands) but I can't recommend any single program as I'm unfamiliar. What I can recommend through experience is that picking one program and sticking to it ended up helping me in the end. Studying multiple different retriever programs allowed me to try different techniques when I ran into speed bumps with my pup, but the programs will usually start doing minor things in the beginning that lead into advanced concepts in the end.
