Need Recommendation for Coffee Shop

I cannot make a decision for the life of me. Originally considered just a Beosound A9 in the corner. Now have moved on to considering two different stereo pairs of bookshelf speakers on opposite sides of the room.

The goal is not massive bass like what might be needed for a proper home theater setup. This is easy music listening with the occasional ability to pump it up for a celebration. MAYBE I’d add a sub down the road. But I’d rather spend a little more on a slightly better speaker up-front and not HAVE to do the sub (I know, probably sacrilege to many in here to not do a sub with bookshelf speakers). Main goal is excellent separation/clarity and to fill the room with sound. Atmos/Spatial Audio stuff not that important. Standard stereo goes a long way as long as there’s a good setup otherwise.

Room/space is 25 x 30 feet in the front area where customers will be. There’s an area in the back of similar size that we may add one speaker to in the future.

Considerations so far started with Triangle BR03/04 and have since moved to Triangle Comete Ez (way down in price from where they were and great aesthetics), ELAC Debut 3 (either of the sizes), Wharfedale Diamond 12.2, even KEF Q150...budget is a bit all over the place there. But I’m trying to figure what will work well. I don’t want the sound to sound so one-sided in the room, which is why we were thinking of putting TWO pairs on opposite sides of the wall (on bookshelves, not on stands). Bookshelves aren’t that deep at all (though we have good vertical space), so that’s another concern.

And then finally, the method will 100% have to be Airplay 2. So we’re thinking of some WiiM amps or something similar (one for each set since they’ll be separated) and then play to both from the airplay device.

Anyone have experience with filling a shop like this with sound on a budget? I’m thinking it’s just going to cost me an absolute minimum of $1,000 to not be complete garbage and likely $1,500-2,000 for what I actually want -- would really like to stay under $2,000 all-in. Obviously open to suggestions. I even thought about peppering the ceiling with Bose cube speakers for a minute. So...open-minded to say the least.

Also, for what it's worth, if someone recommends something that I end up going with, and it works out, I will totally Venmo/zelle something to the first to offer that suggestion for the help. Thank you in advance!
