What is size of mirror? Looks pretty small for the length of that wall? A nice console of fair size with a chair would be nice. You might be able to put the mirror to left of center and put a decorative piece such as large arrangement of branches in black container for contrast. Let me do a little mock up to show you concept.

I believe that a mirror this size is meant to be placed on the floor, leaning against the wall. How were you planning to use it with a console? Side by side?

I didn’t know this was leaner mirror. How long is that wall. I don’t think a leaner mirror would be best on this wall. Here is one concept.

You look like you need a drop zone and I don’t know your style preferences, but I think a bench with possibly storage would be a nice way to use this large area.
