EDIT: I just re-read your comment and realized you were asking specifically about ARC cards. Sorry I don’t have any experience with them. I’ll leave this comment here though in case it’s useful in some way.
Everyone seems to always recommend AMD cards for Linux but at least in my experience I’ve had no issues with Nvidia cards. I have a 1070 in my home Proxmox server passed through to a Debian transcoding for Plex and Jellyfin, and in my gaming machine I dual boot Debian and my 4090 works just fine so far (including HDMI sound). I just installed the latest drivers on both machines and they “just worked”.
I don’t personally have any issues with using proprietary drivers, but I understand why people prefer AMD for the open source drivers if that’s important to them. I just wanted to chime in with my experience because a lot of people will outright dismiss Nvidia cards for Linux saying they don’t work well, regardless of the politics of the drivers. At least for me they work fine.
