I created this mesh by applying a boolean modifier to two cubes. I now want to convert the n-gons to quads by creating loop cuts. When I do this by snapping the loop cut to the vertice of the inner cube, it creates weird geometry, where the new edge isn't connected to the vertice.
I realized I can create what I want by using the Knife tool, but I'm trying to better understand the loop cut tool and wonder how I can fix this issue.
I can see your thinking, but I believe this is intended functionality. The edge loop is seperate from the boolean edge, thus layering them on top of each other will produce broken shading. If your only goal is to go from the ngons to quads I would suggest creating new edges between the boolean'd corners and the original cubes corners like this:
Additionally, if you really want this edge loop, you can create vertices on the edge loop you created above the boolean'd hole vertices, then join the vertices using M > At Last (assuming you selected the hole vertices after you selected the edge loop vertices) like this:
Surprisingly, (at least, to me,) if you switch the 'Split Edges and Faces' option on, in Header > Automerge, new vertices get cut in to the fresh loop, if GG is snapped:
But IMO, it would be preferable always to look for a way without Booleans, if you can.
In this case, possibly, using a CtrlB bevel on crossed loops, an inset, and an extrusion:
