According to...?
My actual testing on a MacBook Air M2. I never achieved even close to 1 Gig, generally below 90 Mbps. Getting the Anker 1 Gig adapter and I was able to achieve much higher speeds. The adapter sold in the Apple stores is made by Belkin. The Belkin adapter uses the Realtek RTL8153 chipset and MacOS does not have the proper drivers up through Ventura 13.2. Using my Surface laptop I achieved much higher speed than on the Macbook Air. The adapter was not defective.

Others with issue.

For an M1 MBPro, what kind of an Ethernet 2 USB-C adapter is apropriate to buy? One that supports 1GBps or 2,5Gbps?

If your network supports 2.5Gig, buy an adapter than supports 2.5Gig. Otherwise buy an adapter that supports 1Gig. Why is this a question?
The 2.5 Gbps Ethernet adapters seem to have better driver support. I went from 120-150% CPU when using a 1 Gbps adapter to almost nothing with the 2.5 Gbps adapter. The D-Link 2.5 Gbps also seems like to draw much less power.

People have been predicting the demise of DLink since the early 2000s, yet they somehow are still around.
It's hard to believe there's a company that makes more trash electronics than TrendNet, but then you see DLink.

I've had a Trendnet ethernet switch that's sitting next to my Mini and has been working just fine for many years now.

Why get a dedicated Ethernet adapter and not go for an adapter that has many other ports and an Ethernet port?
I run mostly on battery and I have a specialized need for Ethernet at work (connecting to an embedded Linux device for development). The Ethernet adapter uses about 1.5 W. I doubt a dock would come close to that.

I have a lot of trendnets here, no problems most of the time as simple switches, but if they're smart switch, they sometimes lose their smarts, but continue to work as normal switches. I have some DLinks too, no problems. Some of their USB stuff is crud though.
