What are your objectives? Do you want an a small, all in one, do you want separate speakers? Do you like the idea of an amp/receiver+speakers? How much do you want to spend?
My suggestion is an Amazon Echo Flex or Echo Dot + amp that will be hidden + stereo speakers. The Amazon device can be a BT receiver from your phone or other device that you used in the past. The Echo acts as a BT receiver and sends the sound to the amp via a 1/8" stereo plug.
This is one of the "best sounding" options but not the easiest to setup. The easiest to setup would be either an all in one BT speaker or BT speaker pair.
I've heard good things about the Klipsch options

Those are examples and lots of brands make such speakers. I don't have any specific models I recommends but it would probably help if you can narrow down an option.
BTW, in my living room I have this setup which I do recommend.
NHT SB2 - The SuperOnes are less expensive and still really nice.

Extron XPA 1002 amp
https://www.extron.com/product/xpa1002
This is an professional installation amp. They are very power efficient when in standby. Mine came from a remodeled classroom. On ebay they can be had for under $50.
My input is either a Chromecast Audio or Logitech BT adapter. The only part of this system that is seen is the speakers. The rest is hidden away. It sounds good though the placement of the speakers is about keeping my wife happy vs best acoustics.
So, yeah, that system is my recommendation
