I had to connect a work Macbook to Ethernet. It didn't have a port so I bought a no-name brand USB-to-RJ45 adapter off Amazon. Come to find macOS doesn't have driver support for the adapter even though Windows and Linux are both plug and play. And I wasn't willing to do some backdoor process to install drivers on a work laptop. I had to buy a Apple branded adapter, which was 2x the price and only USB 2 vs the other one being USB 3.

I have a random off-amazon 2.5gbps usb ethernet adapter on my M1 and it works great. I did specifically make sure someone said it worked on a mac, but wasn't sure about on ARM.
