I already purchased the below which should be sufficient I think?

-surge suppressor receptacle (https://www.amazon.com/dp/B0039UUMJM)

-3 fresh hdmi cables at 6.6 feet length - it's not a long distance (https://www.amazon.com/dp/B08M9HND4F) - I already have one trusted cable I'd keep with the new tv in case there's some issue with the new ones since I believe the tv has 4 ports

-1 fresh ethernet cable for the tv itself - though I'll probably use the streaming stick mostly (https://www.amazon.com/dp/B00N2VIALK)

-the tv itself comes with a flush mount

Good luck. The thing with cables is the version numbers don't matter - just that its a good quality cable. Also price doesn't mean anything (i.e. more expensive doesn't matter unless buying very long HDMI cables). So long as it is rated for 18gbps you will be good. If you find you get issues with the amazon get this https://www.amazon.com/8K-HDMI-Cable-Highwings-Braided/dp/B08M9HND4F/ heck get this one and the amazon basics and send one back after you have tested, these are like $8 :-)
