Bridge Performance over 10GbE; SFP+ vs 10GBASE-T?

In short: all other things equal, would the lower latency of SFP+ (fiber) vs 10GBASE-T (CAT6a) be noticeable when loading thousands of photos into Bridge? 

Now the longer explanation: I have the option soon to upgrade my networking equipment and NAS, and happy to spend some $ to make things as *snappy* as possible, especially with loading/importing media for the first time. Right now i have a decent 10gbe setup over CAT6a direct to my QNAP -- and it's good -- but not quite as quick to load media (RAW photos usually) as from a locally connected SSD. I'd love to narrow that performance gap if possible. Wondering if there might be a improvement with Bridge performance by switching to SFP+. On paper, it appears the biggest practical difference is that SFP+ has better latency, so with loading thousands of images, i figure it might actually be noticeable. There are two concurrent users on our current NAS.  And for what it's worth, when i load photos they are usually from a section of the NAS dedicated to 'active work' with a 3 SSDs in RAID0, and my local cache drive is a super fast M.2 SSD... so drive speed isn't a limiting factor.  I also know there are many other factors that go into fast network performance, but right now i'm trying to focus on this one thing (fiber vs twisted pair).

thanks!
