Is a home theater even worth it or doable?

Please be honest with me. I'm a huge TV  movie fan as I'm sure many of you are, and in my youth I used to have a Denon setup, blu-ray, etc. I loved the experience. Fast forward 25 years and now I just stream my tv and movies off Netflix, HBO Max, and Hulu. We are doing a new addition where we have an open space concept. I see myself continuing to stream in the future, but would like a clean sound at least. I am treating myself to an 85" TV not sure the make model yet, but I want a big one. Does it make sense for me to even invest in something more then a sound bar given my streaming and open concept? If so, what type of setup should I consider or if I should prewire something up and where would that be? Thanks for your advice.
