8K TVs would use HDMI.
Apple’s TB4 1.8m (5’11”) cable is $130, so, yes… other 2m TB4 cables are about the $60 price too.
8k monitors are out there; Dell released one (not USB-C or even TB/USB4-based) 32” one a few years ago, which got good reviews but was normally noted as being expensive and likely only of benefit to professionals. I believe you can find TB4/USB4 8K monitors in the market now if you wanted one…
Regardless, no USB 2.0 cable will support a video signal, whether 8K, 4K, 1080p or 720p.
USB4 (or TB3, but preferably TB4) is required for that.
[EDIT] Actually, USB 3.2 (and TB3) cables and up may carry the DP alt-mode, it is just that USB4/TB3/TB4 certification specifically mandate them to support the video (DisplayPort) alt mode. Some examples of USB 3.2 cables supporting DP alt mode:

Yes, HDMI is a standard both TVs & monitors can use; DisplayPort is the PC-focused ‘alternate mode’ that USB-C cables with the extra wiring enable, so will likely gain usage going forward.
