DIY Garden room - Equipment help needed please

[AVRookie99]

Hi, Ive spent the past six months building a garden room (see attached picture), the outside is nearly complete, just need a few good days of weather to finish the roof and finish the cladding on the front. The room internally is approx 6 x 4 metres. Im looking at having a 65inch tv fixed on the right hand wall. I'm looking for advice and any help with regards to speakers, surround sound, soundbar etc. The walls and ceilings haven't been plasterboarded yet so its the perfect time to run cables etc. Do you think ceiling speakers would be a good idea, if so, how many?

Thanks in advance for any advice.

I think you need to be a bit more specific about what you want to achieve with the space TBH. What's the room going to be, do you have a budget in mind and other specifics are required to give a decent answer.
