Everything you need: KCC Industries 1-Gang Recessed Low Voltage Cable Plate with Mounting Bracket +UL/CSA Listed Safe+ (2-Pack, White) https://www.amazon.com/dp/B07FQP5Y9Z/ref=cm_sw_r_sms_apa_i_6XGXCbV8Z9S7P
Also sold at home Depot, would save a few bucks that way.
If you're literally just running through one wall from one side to the other just run the cable directly through the wall. If you want to hide the hole then get a pair of the media plates used for TV's like these:

Then run how ever many cables you want. Otherwise you'd literally have a 3" patch between one side of the wall and the other.
Honestly I'd run one cat6 cable to the switch you linked to and connect everything to that. It's unlikely you'll be using more than one or two devices at the same time, and it's also unlikely your internet is fast enough to keep up with the gigabit link anyway.
