There are two seats in the middle of the room that seem to be the sweet spot. Draw a line from between the two seats to the front of the room. Slide your AV rack so that the centre speaker is on that line. That will make your set-up symmetrical (balanced left to right).
Your pic has the 3 front speakers at the same height. That is what I would do as well. When sounds move from left to right across the soundstage, they won't go up and down in height, which happens on set-ups where the centre speaker is at a different height than the L/R speakers.
Also in your drawing, you have the L/R speakers right next to the AV rack. You can spread them apart (symmetrically) to get a wider soundstage. Of course be careful that your right front speaker isn't too close to the stairs.
Finally, even in this day and age of surround sound, the front soundstage remains critical. That is where your attention will be focused, whether watching a movie or listening to music. The front right side of your room is open while the front left side has a wall. This will cause an imbalance in the reflections. At some point in the future, you should consider putting a large absorber on the left side wall near the front of the room to mimic the open right side. That will restore left to right balance and make your soundstage consistent on both sides.
