I don't think $3000 on a soundbar will get much value over units that are 1/4 and even 1/10 that cost.
I have a Yamaha YAS-109 that is discontinued but there appears to be a successor that is similar, the SR-B20A. It is not up to the standards of my Hsu 5.1 HT, but the YAS-109 has great and to my ears accurate sound, with some useful EQ settings on the remote including the self-explanatory ClearVoice, which actually sort of works.
I found every soundbar-included subwoofer to be inferior to a "real" subwoofer and I listened to just about all of them - Sonos, Bose, Sony, JBL, TCL, Roku, Samsung, LG, etc.
The Yamaha above is the soundbar I would go with because it has a subwoofer output and does not come with an inferior OEM sub. I paired it with a stealthy Dayton SUB-1000L and it sounds fantastic. <$300 total in 2021 but probably more like $450. The hardest part was getting a well-shielded 20' RCA cable for the sub.
