Unfortunately I don't know much about hypertrophy training, so I may be wrong with a few of the things I'm about to say.

I think that yes, higher reps at lower weight in the 8-12 rep range will generally target hypertrophy more than strength. You wouldn't necessarily want to do a strength program with higher reps to build hypertrophy however, as things like recovery will differ at higher ranges. I want to say that there would be diminishing returns fast if you only did compound exercises at high rep ranges.

I also see many hypertrophy programs will incorporate more exercises which isolate muscles at higher rep ranges than strength programs. I'm sure that this has to do with recovery, since you'll often see split programs like PPL (push pull legs) which offer more days in the gym split up between different muscle groups.
