I'm really not sure about this, but to my knowledge, the F16 is the only fighter that did go for a side-stick; the F18, Rafale, EFA, MiGs and Sukhois all use conventional positions between the legs. I can't remember seeing photos of the F22 or F35 cockpits (the latter seems a moot point since I have doubts it'll ever enter service), but I think they have centre-sticks too. I suppose it's because of the F16's then ground breaking G-pulling ability and the fact that the pilot had to be so reclined and supported, while later aircraft with comparable agility use full-body g-suits. - the F16 was designed as a relatively simple fighter and would not have needed many cockpit controls, though it later developed into a more universally capable aircraft. The fact that they manages to squeeze in so many extra interfaces on later models is impressive. So, I think the F16 remains almost unique in that respect - I think someone else mimicked it, perhaps an Indian or Chinese fighter - I really can't remember where, but I seem to very vaguely recollect it being once. It is also unique in having a fixed stick that senses pressure rather than a moving stick which senses displacement. Regardless - it obeys convention of a right-hand operated stick controlling pitch and roll.
As for power control convention between aeroplanes and helicopters, technically they both obey the same convention - they are instinctive in that the aircraft will move in the direction the lever is moved - forwards on thrust levers/throttles increases forwards acceleration, upwards on a helicopter's collective will accelerate the helicopter upwards. I'm curious about the V22, though, as to whether they made it primarily a helicopter with aeroplane mode, or made it an aeroplane with helicopter mode (like the Harrier).
Anyway, as you said, you can jump from one pit to another and know what's what. I can jump from my B737 into an A380, and while the aircraft is totally different in operating systems, I could fly one if I had to - the most confusing part would not be the flight controls but the automatics, but in direct law, it'd be simple (if a little strange with that attitude-hold behaviour).
