If you're usually manage torrents from Windows, my answer is: Transmission Remote GUI. I'm running a few Docker instances of Transmission and transgui has given me the best experience so far. It's lightweight (~5 MB RAM), handles remote directory forwarding, and can control nearly (if not all) the functions/controls in Transmission, to include manually selecting files. I definitely prefer a desktop client... Source: about 2 years ago
I am using Transmission V2.94.0 since 2019 on my TS-251 with no problems. Just make sure to use 3rd party Transmission Remote GUI (I am using version 5.0.1) which is IMHO much better for torrents/files management than Transmission Client itself. https://sourceforge.net/projects/transgui/.

Haven't checked if it's available for FreeNAS, but - Transmission is awesome. I run the daemon headless on a Pi 4, and control it via https://sourceforge.net/projects/transgui/. Source: about 3 years ago
