Small amp or all in 1 choice?

My wife and I are in the process of building a small 850 SF Florida vacation home. It will be ready early fall 2024. We are going to put 4 ceiling mounted speakers in the entertainment/living room for viewing tv and streaming music. The TV will be on the wall above a small fireplace with a 14" X 60" granite shelf above the fireplace to hold the electronics, router etc. I am going with a simple "lean and clean" look so no visible speakers in front. I want an "All in One" unit that will accept an HDMI/Arc connection for TV and also have the internal DAC for streaming background music. I was looking at the SVS wireless Pro soundbase but it only drives 2 speakers so I either need to find a similar all in one with HDMI ARC input that can power all 4 speakers or find a small outboard amp to drive the other pair of speakers. My wife is sensitive to to the shrill sounding cheap amps so that needs to be considered.  I really do not want to put a lot of money into this as the house is expensive and taxing the funds. We are starting from scratch here and EVERYTHING is new, tv, appliances, furniture, etc. I looked at the Cambridge stuff but $3000 is too much money for the model that drives 4 speakers so I think I just need to find a nice outboard amp to mate with the SVS. Any suggestions as to what to look at? I've been through the stuff on Crutchfield. I guess I'd like to be around $400-$500 for the amp, of if there is a all in one that drives 4 speakers and has the HDMI input like $1200-$1500 all in? Any ideas? Also I know I could just buy a HT Receiver but wanted to keep things smaller in scale to fit the shelf @ 14 inches deep. A receiver won't fit.
