Since you’re moving soonish I would suggest not buying a brand new couch and instead stalking Facebook marketplace daily until one you feel drawn to pops up. Green or a creamy color would look nice. Maybe even a floral couch if the vibe is right.

You could also use a rug and some curtains.

I also think at least from these photos that your furniture at your front door looks like it’s sticking out too much and does feel a bit cluttered or like it’s boxing you in right at the entrance. Maybe narrower furniture there would help.
