Would I see a benefit?

Absolutely, I understand the frustration with sluggish file transfers. While upgrading to Ironwolf Pro drives might offer a slight improvement due to faster spin speeds and increased cache, the real game-changer for significant speed boosts would be considering SATA SSDs. Their speed in handling large file transfers is unmatched and could provide the noticeable improvement you're seeking. If you're aiming for a substantial upgrade in performance, SATA SSDs are the way to go. It's worth noting that investing in a 4-bay NAS with drives configured as RAID 5 could be a more substantial but effective solution for enhanced performance, especially when dealing with large image files.
