One thing I did not do was look at the eyes. I'm aware of other spiders that may have a violin-like markings, but none the same exact color and physical attributes shared by confirmed fiddlebacks.
If you see the picture I shared earlier in this thread, all of the supposed fiddlebacks I've seen in my house the last few days look exactly like it, just different sizes.
I see on the Wikipedia that one of the closest resembling spider is a cellar spider, only because of the violin, but otherwise looks nothing like a brown recluse, in my opinion:
I also saw the Southern House Spider linked above, which are similar, but with slender bodies and uniform coloring. All of the spiders I've seen have darker, rounder abdomens.
Some of the crevice spiders look like fiddlebacks,

Some of them will have a wider stripe than that, it's hard to tell when they're moving 400mph across your bed.
