Trying to set up a new light fixture and confused by wire situation!
I would verify that the blue is your switched hot. It is unusual to have the white and ground spliced with a single hot lead but since the place is probably wired in conduit they may not have brought the other hot into the box (as part of a multi wire branch circuit). I believe the fixture black should go to the blue then the white &amp; ground to the white and ground on the fixture.
