While a home theater system with individual speakers sounds better than a sound bar. I think in your case I would recommend considering a sound bar.
I would recommend keeping your eye out for a sale on the Sennheiser Ambeo. You will get top notch natural sound with a simulated surround sound and great bass (you can add a subwoofer later if you have some neighbors you do not like). Over 85% of the sound comes out the center speakers of a surround system, and the Ambeo throws a pretty convincing sound field on both sides of it… so that would be 95% of the sound from a surround system. You avoid the wires and hassle of placing speakers all over the place and it is a very substantial step up in sound quality.
I have a full blow home theater in our living room with sound that can shake the house to it’s foundation (see my UserID) and a Sennheiser sound bar in the bedroom with our 65”. We previously had lessor sound bars. The Ambeo is the one to get.
