When it comes to finding the right seedbox for your needs, it sounds like you're looking for something with robust capabilities. Offshore Dedicated Server could be a great fit based on what you're seeking. They typically offer generous storage options, unlimited traffic, and solid performance for running apps like Sonarr, Radarr, and Plex seamlessly.
I've seen Offshore Dedicated Server recommended for their privacy features and the ability to handle private tracker torrents effectively. They often include Rclone access, which is handy for managing and syncing data.
