I think I'll go with a drop-in panel, marked to note that there's a
junction box below and add 2 finger holes marked with "Lift Here To

I cut the floorboards back to the center of the joists, so once the
panel is dropped in, it can't fall out, tilt or shift, With that
solution, the junction box and fixture will be accessible from above.

That'll work, too...but if you thought ahead and were careful in the
removal process you should be able to just lay the flooring removed back
in the opening...
