I honestly don’t know who to point you to for both olympic lifting AND powerlifting programming.
All I can really give you are my two cents, which are probably worth about .01 cents cause I’m not a particularly strong powerlifter or olympic lifter haha. But like yourself I love all kinds of lifting and put a lot of time into researching programming and whatnot.
Common sense tells me that your best bet would be pretty simple: start most sessions with olympic lifting. Snatch, clean and jerk, or power snatch and power clean and jerk. Because of how insanely technical they are, you need to be doing those lifts fresh, and you need to be doing them very frequently in order to perfect technique. So I would be training at least 5 days a week, doing an olympic lift to start each session. Doesn’t have to be super heavy, most days should be light enough that it is more or less technique work.
Then, after you are done olympic lifting (for example, say you did 10 snatch singles at 75%) move on to a very basic powerlifting program. This will be the time to really hammer away at heavy weights and get you stronger. While you might be a little tired from the oly lifting, the explosiveness of the lifts will prime you to be moving fast and explosively when you squat, pull etc. I would probably do snatch variation, followed by a ton of squatting as one workout, and clean and jerk variation followed by bench and pulling as another workout.
They key, I would bet, is not overworking the olympic lifts. Take 20-30 minutes to really hammer technique, don’t miss a single lift, and just get GREAT at them. Then, take 30-45 minutes (once you are all warmed up and explosive) to crush some heavy weight for a lot of reps on the big 3, and just kick your body’s ass. If you get significantly stronger at squatting and deadlifting, and significantly improve your olympic lifting technique, I have a feeling your oly lifts will improve significantly as well. Imagine you take your squat from 300 lbs to 500 lbs. I’d bet that, even if you didn’t clean that ENTIRE time, your clean would probably go up quite a bit haha. Now, imagine you up your squat 200 lbs, and you have been cleaning 3 x a week, never missing lifts and always focusing on perfect technique.
Obviously this probably isn’t the best way in the world, but for a guy who isn’t trying to be an olympian, I bet it would work pretty well. Probably the best way would be to do the oly sessions in the morning, and the power sessions in the afternoon, but I think combining them would work as long as your are modest when picking oly percentages. This is how I would set it up
day 1) Light snatch variation / heavy squats (high bar or front squat)
day 2) light clean and jerk variation / heavy bench / rep effort or dynamic deadlifts (probably clean deads would be best)
day 3) Rest/mobility
day 4) heavier snatch variation / rep effort squats
day 5) heavier clean and jerk variation / Heavy deads / rep effort bench
day 6) Cleanup day - oly lift variation or variations, accessory work (rowing, curling, pressing, whatever you feel you need that week)
day 7) rest/mobility
Again, I have no idea how useful this is to you, but if it were me and I couldn’t find a pre-made program that worked, this is how I would do it.
