Yes grouping is the important part. The next important part is labeling.

For example, I have a variety of USB C to USB C cables but they each have their own capabilities. Some support high transfer speeds, so I keep them around for connecting SSDs, while others are just USB 2 speeds so they are strictly for charging.

Another case is I have a very specific USB C to USB C cable that looks incredibly generic, but it is for connecting a screen tablet to a laptop because the manufacturer decided to make the port recessed, so only their cable fits. If this cable wasn't labeled as for a specific device, I would have donated it years ago.

It is some effort, for those who don't like to tinker with tech I can understand why they just shove them all into a box in the back of their closet. But I find that culling my cables at least makes me aware of what I have and don't have.

One other suggestion I have is just buying a longer cable than you think you need because eventually you'll have the need for it anyway. I have so many 3.5mm aux cables because I kept changing my desk set up and needing to buy longer and longer cables. If I had just bought the longest cable I could have at the time I would have saved myself some headache.

Another tip is adapters. Sometimes it's easier to just have cables of one type and a bunch of adapters for when you need them rather than having a ton of different cables for each possible scenario. I used to have a mix of RCA and 3.5mm cables but never had the right combination of what I needed at the time. Eventually I caved in and just bought a ton of adapters so I could standardize all the cables and use adapters as needed. Same with USB C cables.
