Help deciding on a soundbar

I know this has been asked but I have certain criteria and want feedback. Currently have a Bose Cinemate II system. Tired of wires everywhere, optical cable, and it’s starting to have issues where dialogue is low and overpowered. Granted I’ve had it since 2009. Want to upgrade but am limited on what I can do. Have 3 kids. Want less hassle. Can’t have rear speakers. Tv mounted on the wall. 65in TCL Qm7. Want something that is similar to the Bose set up. Speakers are below tv and sub is to the side of the tv stand. Want something that has clear dialogue in a loud scene. Bass is there but doesn’t need to shake the house. Watch mainly movies, shows through a Fire cube. No music streaming. Xbox series S as well. Possibly future expansion but not necessary. Room is 15 by 15. Sit about 12 feet from tv on a couch. Budget preferably $600 or less.
