Help with designing a theatre room

We recently moved into a new house which has a bonus room above the garage. Half of the room is being used for cardio/yoga and an office. The other half of the room we would like to setup as a theatre.

Our primary uses will be for movies/shows from streaming services on an Nvidia Shield Pro, sports, and video games. We don't need to blast sound (sometimes movie theaters are too loud for us). We just want it to look and sound good, especially the center channel for dialogue.

The room has a few windows, but we will get blackout curtains and the walls are painted dark grey already. The room also has a ceiling mount, power and HDMI ran for the projector. It has a power outlet on the floor we would like to use for the powered recliners, so those distances can't really change. With the odd slopes on the ceiling I'm not sure if it's possible to easily setup Atmos speakers, but we would like a receiver that can handle that if we decide to try to add them in the future.

We would like to keep the budget around $10,000-$12,000 if possible.

I have been reading a lot of posts and see that the Epson 5050 is highly recommended. With our content I was thinking a 16:9 screen makes the most sense, and with a 11'6" viewing distance something around 130-140" screen. Does this sound right? We typically prefer to sit around 1/3 of the way forward in a movie theater.

After looking at some of the mid range roundup reviews I was leaning towards the Chane 2.4 for LCR speakers, with an HSU VTF-3 MK5 subwoofer. Are those good options, should I be considering something else? Are there any recommendations for receivers and also surround speakers? Is there anything else I'm missing?

Thanks
