This used to be true, but unfortunately, like USB-C the game has changed completely.
The downside to standardization is that if you keep the same physical form for multiple iterations, the internals can change. The specs of the source and receiving ends have gone through tons of changes since 2015 and old HDMI 1.4 Cables don't have the same standards to transmit high speed signals from things like PS5, Xbox, Apple TV etc.
Additionally because they require programming and HDCP (a verification handshake between the 2 devices it connects) when companies cheap out they may not properly program them.
That being said, you don't need spend an arm and a leg, but don't get shit either. Generally speaking, buy the cheapest version HDMI 2.1 from a reputable brand or vendor. Definitely not from Amazon anymore, a TON of products labeled 2.1 are actually 2.0 or worse, 1.4.
USB is a nightmare.
I only realized recently that my steam deck wasn't charging as well with any old wire. And that's when I learned that different wires and adapters have power limits.
I'm not a expert at these things though.
The steam deck won't pull past 3A anyway (all usb C cables are rated for 3A), so unless you're using a USB-A to C cable, you should be getting full speed, unless the cable is damaged.
This is true, specs between different versions are different.
That said, it's definitely NOT a reason to buy expensive. I can find 1.3 HDMI cables being sold right now at over twice the price of a legit 2.1 cable...
