Sure have, within the last 2 weeks when I helped a coworker migrate to a new machine! Both were November 2024 MacBook Pros, so Apple's current top-of-the-line laptops.

Running over Wi-Fi dragged on interminably and we gave up several hours in. When we scrounged up a could of USB Ethernet dongles and started over, it took about an hour.

So yeah, my own personal experience confirms exactly what I'd expect: Wi-Fi is slow and high-latency compared to Ethernet, and you should always use hardwired connections when you care about stability and performance more than portability. By all means, use Wi-Fi for routine laptop mobility. If you have the option, definitely run a cable to your stationary desktop computers, game consoles, set-top boxes, NASes, and everything else within reach of a switch.
