Does this technique only work with systems that are edge-on so that the star light passes through the exoplanet atmosphere? Or can this work with reflected star light for systems that have orbits that face us?

Edge only. Fortunately, most of the exoplanets we know of were discovered by that exact method (by space telescopes that stared at a patch of stars for months at a time https://en.wikipedia.org/wiki/Kepler_space_telescope ) so it's just a matter of working down that list.
