After spending years in rented large houses, its time to move to my new small apartment

OPTION 1 - Use wall A for screen and partition the open area 'P' to create a rectangular closed area. There would still be open areas 'x' and 'y'.
OPTION 2 - Same as option 1 + another partition P2 to close out the area. This would most likely be glass slider door to give a sense of space.
OPTION 3 - Use wall 'B' for screen and partition 'P'. This would give much more space overall but am concerned about the open walkways - X, Y.
One thing I am really concerned about is being able to enjoy Movies without disturbing neighbours. Any recommendations to avoid this.
I am also looking at doing some bit of acoustic treatment like using rockwool OR using Horizon QKit Room Kit. Any reco in this area.
Thanks.
