How can you see what SMB? version your Mac is running ?
macOS Big Sur still supports all three of AFP, NFS and SMB as a client - at least on Intel computers. It does not offer support for AFP as a server.
I happen to know that it is AFP on the source because I initiated the connection. The source was an Apple Time Capsule, which only allows connections over AFP (it also supports SMB1, which is absent by default on both modern Windows and macOS).
And my destination was a Windows Server 2019 that supports SMB3. SMB has been designed to use the highest common supported dialect, which is SMB3 with both macOS Big Sur and Windows Server 2019.
The two screenshots below are from network traffic captures between my Mac on macOS Big Sur and my Windows Server 2019 server. It shows what dialects macOS Big Sur supports for SMB (SMB 2.0.2 to 3.1.1) and what it elected to use: SMB 3.1.1. I also did a transfer to confirm it.

P.S.: Do you speak French? Because your autocorrect might have corrected some words like "offered" and "access" by "offert" and "accès" respectively
