Of the two, I'd choose the 1060. If you aren't also using it for gaming, that is. If you are using the 1060 for gaming while keeping Jellyfin running in the background, use the Intel iGPU.
Jellyfin 10.10.7 (Docker)
Ubuntu 24.04.2 LTS w/HWE
Intel i3 12100
Intel Arc A380
OS drive - SK Hynix P41 1TB
Storage
4x WD Red Pro 6TB CMR in RAIDZ1
