I want to keep the two speakers and the tv mounted where its at. What furniture would look best in this small space. Would like some decor advice please

I have a lot of wood furniture already so I'd like to incorporate more color and texture. going for eclectic natural with minimal mid century color and pieces. right now it's missing the eclectic and I actually enjoy the "dopamine" style. I'm open to different materials like enamel, metal, glass and gold. I want my little house to be cool And right now it's boring. I want to replace the entertainment stand under the TV and some sort of shelving- so I'd like suggestions on that. I'd really appreciate some help. I've been focused on keeping the house clean and organized that decorating has taken backseat . thank you!
