HDMI Cables/Switches for Home Theater Setup

I just started ordering the stuff for my home theater system, and I'm pretty confident on most of what I've chosen, but now I'm wondering about the nitty gritty. Specifically, the cables. My goal is to connect my Hisense PX3 Pro (and Vividstorm Barcelona III Cabinet) to a Sonos setup (Arc Ultra, x2 Sub 4s, & x2 Era 300s), a Panasonic UB820, an Nvidia Shield TV Pro, a Switch 2, PS5, Xbox X, & a ROG Ally.

I'm thinking these Monoprice 8k cables, a 6' from the Sonos to the projector, and 3' from the other devices to the projector, and into a UGreen 5 Out-1 In Switch. Any thoughts as to whether this would work, or if there's better stuff to be had? I've never made a home theater before, and I want it to be as good as possible.
