Nukes are only fun when they've got an atmosphere to send a shockwave through. In zero-atmo, all they do is act like a regular dirty bomb, and most spaceships are expected (and designed) to handle far stronger radiation.A beaming block is only so strong. Given time, it can be worked past. Especially when the source tech is primitive. (wraith had ancient-level tech, whereas most others have goa'uld-level)

Beams don't go past shields either, however at the battle of the supergate they were going to use rings to beam nukes across however they were raped before this happened.
