Apartment Audio Solutions

So I’m looking to spend money on a new TV and audio setup.

I have two bedrooms, a living room, kitchen, an office, and two bathrooms that I’d like to fit with speakers. I do rent so I do need wireless.

For the TV in the living room and one bedroom I want a sound bar, but am planning for bookshelf style speakers for the rest of the rooms. I live in apartment building so I want to avoid a subwoofer. There’s decent sound proofing though, and I don’t plan on cranking the volume for any of these.

I want to be able to combine any rooms with each other and play music from any tv or Spotify.

Im currently looking at Sonos systems, but want to consider something more self hosted.

I wouldn’t know where to start looking for good systems. I imagine music assistant would handle the logic of what I need, but no clue on speakers and amplifiers.

Any ideas?
