Hallway lights have a reputation for being an afterthought, the fixture you grab last and cheapest because nobody lingers in a hallway long enough to judge it. I think that is backwards. A hallway is the first thing you and every guest sees, and overhead light in an old building is almost always harsh and yellow and unflattering, so this is the one spot where a decent fixture changes the whole entrance to your home, not just the hallway itself.
A hallway light has to get along with whatever is already doing work nearby, usually a console table, a mirror, maybe a row of coat hooks, and it should not compete with all of it for attention. If the hall is narrow, which most are, you want something that sits close to the ceiling or close to the wall rather than hanging down into the space people are walking through, because nothing says bad planning like a pendant you have to duck. Measure the width of the hallway before anything else, not just the ceiling height, and if you are under about three and a half feet wide, go flush or semi flush rather than anything that swings. The common mistake is choosing a fixture sized for how the room photographs rather than how it is actually walked through twice a day with your arms full of groceries.
For color and finish, the ones that stay easy to live with over the years lean toward warm metals, brass, bronze, aged nickel, or simple white and black, because a hallway often connects two or three different rooms with different palettes and the light fixture has to be the neutral thread between them, not another decision you regret. Glass that is frosted or ribbed rather than clear tends to hide dust and bugs better too, which matters more in a hallway than anywhere else in the house since nobody remembers to clean it.
The difference between a good one and a disappointing one shows up the first time you touch it. A well made fixture has some actual weight to the metal, the switch or pull has a clean, solid click rather than a rattly give, and the glass or shade sits flush against its fitting with no visible gap or glue line. Cheap ones hum faintly after a few months, or the finish starts flaking at the screw points within a year, which you will not notice until you are staring at it every single day on your way out the door.
If I had to put one of these somewhere first, it would be the entryway, right where you drop your keys.
