This stuff will now go in the basement is there a window in that space in the basement ? The light fixture is an easy change maybe even something a bit of fun for a baby's room

You select the light last, when you have a PLAN for the nursery, the look and feel you want for the nursery. It is nothing more needed than an electrician, or handy man and UNTIL you have your mood, your look for the space ? It is a buggy in front of a horse question: )

Agree with choosing the light fixture last. Do you have a rendering of the room design to post?

Choose something without exposed bulbs. Maybe something fun like below. Definitely have the light on a wall switch with dimmer near the door.
