Burn all the USBC cables with fire except PD. The top PD cable does everything the lower cable does.

IDK I’ve had PD cables that looked good for a while but turns out their data rate was basically USB2. It seems no matter what rule of thumb I try there are always weird caveats.

No, I’m not bitter, why would you ask that?

There are many PD cables that are bad for doing data.

Correct. The other commenter is giving bad advice.

Both power delivery and bandwidth are backwards compatible, but they are independent specifications on USB-C cables. You can even get PD capable USB-C cables that don’t transmit data at all.

Also, that’s not true for Thunderbolt cables. Each of the 5 versions have specific data and power delivery minimum and maximum specifications.

I don’t think this is right. The PD standard requires the negotiation of which side is the source and which is the sink, and the voltage/amperage, over those data links. So it has to at least support the bare minimum data transmission in order for PD to work.

You can buy a single cable that does 40GB and USB4 and charges at 240w.

True but pretty much the only devices that need those are high-end SSDs and laptop docks and in both cases you just leave the cable with the device rather than pulling it out of your generic cables drawer.
