My wife just went to England with a few electronics. Her iPhone uses a USB-A to (proprietary) lightning cable, as does her iPad. But her laptop uses a USB-C to proprietary magnetic-safe connection, and can also accept USB-C directly. Her Garmin Watch uses USB-A to proprietary connector. She took my headphones, and I forgot they need to charge via a USB-mini cable, so neglected to send it. (She just hates this stuff and is under a lot of stress because she is attending her brother who lives alone and had multiple strokes, and the last thing she wants to worry about is a huge tangle of assorted cables and a pile of chargers, along with some UK/US plug adaptors.) The chances of her losing half this stuff are significant, and it winds up being a real PITA. Ideally she should only need a USB-C/USB-C cable and a power supply/adapter. One cable standard to rule them all.

I have a box in the garage that has a huge collection of cables and obsolete apple adapters, including Firewire 800 and 400, and and the version 1 iPod (4G, Firewire, mechanical dial). This is just a huge amount of waste. (Time waste, E-waste, space-waste, resources waste ...).
