Do you mean that the automatically grabbed torrent is slow in qBittorrent? The apps themselves don’t have any idea what is a popular or unpopular torrent, so it may have just grabbed an almost dead one.
You may want to check out TRaSH Guides for some good Custom formats and guides for the *arr apps.
Radarr high-quality release groups

Based on your previous posts I assume that you use Windows as your server OS. I am sadly unable to help you with OS-level issues on Windows. I am also unfamiliar with the quirks of the Synology OS.
You can check if your *arr-apps run as the same user as the permissions on the share (on the *arr-server). The folder and contained files of the share on the Synology NAS should have read, write and execute (rwx) permissions for the user of the share.
