Is this a good HMDI to be using with what I stated above?
HDMI Cables are broken down into 4 Variants:
Standard (4Gbps) 1080i60 / 720p60
High-Speed (10.2Gbps) 2160p30 / 1080p60
Premium High-Speed (18Gbps) 2160p60 HDR
Ultra High-Speed (48Gbps) 8K60 / 4K120 HDR
Would the HDMI Cable from the Cable Company be better?
Subjective. Really how "Good" a HDMI Cable comes down to the Brand Quality., even then most will generally be identical... there is very little difference between an Amazon Basic £5 Cable compared to a Belkin £25 Cable aside from more gold plating being used, perhaps better quality plastics and copper... which can extend lifespan and reduce signal noise., but for the avg. user is never going to really make a difference.
What would be a better or the best to HDMI cable to be using?
There is no "Better" or "Best" Option provided you have a Cable that supports the HDMI Port you're connecting it to.
I'm not going to get into it., but in essence there is a stupid disagreement going down between Display and Graphics Adapter Manufacturers over a dominance of Display Connection... this is why PC Monitors come at a notable premium (when prior to HDMI / DP., they were actually a cheaper option because they were more limited in their application)., and why TVs don't come with DisplayPort.
What's worse is as TVs are segmented in terms of Features in regards to Price., you'll find outside of "Premium" Cost Models; while they'll have all the features you want (and usable in Smart Mode) connections simply won't allow them to do that with most devices.
The reality is that due to said disagreement about Display Connections., with an attempt at Standard Dominance (when both Connections CLEARLY server different markets, so they're not even directly competing) ... well this ends up just causing headaches and frustrations to Consumers.
All you can do is work around said limitations
