3mf files can have location data in the file.  Cura is respecting that data and is explicitly placing the model where it is told to.  In the case of the model you are showing, the 3mf file has defined the Center of Geometry of the model as 0,0,0 and so Cura put that model at 0,0,0 of the printer.

STL files rarely have part location data in the file so Cura uses the bounding box of the model.  That means that the midpoint XY of the bounding box is placed at the midpoint of the bed.  The lowest point of the bounding box is placed on the bed at Z=0.

For some things (like the number boxes of the Translate Tool) the midpoint of the build plate will be considered to be 0,0,0.  For relating to the actual printer the midpoint is X = MachineWidth/2 and Y = MachineDepth/2 and Z = 0.


And if you find that confusing, when you throw in the Home Offsets of the printer - all those points can move.
