For the most part, yes, just about any new pedal will fit so long as you buy a 9/16" pedal and not a 1/2" pedal for kids' bikes.

Yes. I'm using Shimano 105 SPD-SL pedals on a Campagnolo Veloce crankset. No problems at all. The thread profile might be
just a little bit different as mentioned above, but the difference is so slight that it's inconsequential.

I have
Shimano PD-A530 pedals on one bike and
Shimano PD-M324 pedals on another. Both of these are SPD on one side and platform on the other. If I spent much time using SPD shoes on these bikes, I suppose I'd like them more. But most of the time I'm riding these bikes, I'm not wearing bike shoes and I get just a little bit annoyed having to spin the pedal to find the platform side by feel.
When clipping in, I much prefer the SPD-SL road pedals on my road bike. They always hang with the back of the pedal down, which makes it easy to clip into.
