IMO: The space needs to solve two things, and must be designed together.
First, Home Theater, Surround Sound, Light Control. It's solution, viewing location and furniture layout will effect:
Second, 2 Channel Stereo Music System. Sometimes the home theater run in stereo mode will be the music system, you have room for both.
You have a huge wall with no windows, that will help with light control for viewing. I would go to a Home Theater Designer with both plans and photos with ceiling and lighting information. My opinion is a 5.1 surround system is enough, anything further ought to be considered only when designing and building a specific theater rather than this which will be in a multi-functional space.
A proper center channel is very important, and full range front with perhaps a pair of subs, depends as it develops.
My setup, in a smaller space, 13 x 24, is a music system from the far end, and my small home theater is across the width of the room at the opposite end. My primary listening chairs (2) simply spin around 180 degrees, so they are side chairs in the home theater, and primary chairs for music. All my chairs are somewhat acoustically transparent, wicker backed rocking chair, wood frame slat backs, open arms, so sound from either active system is not blocked/absorbed.
Do yourself a favor, get very efficient speakers, that will keep the needed size of amplification down, reducing cost, size, heat.
Once you have the layout(s) solved, the furniture placement/movement solved, then the types of speakers, width of dispersion, can be resolved.
