I am sending the file out to a print lab (ProDPI) and downloaded their ICC profiles to softproof. They ask for sRGB files,
so that is what I export as. Should I be embedding special profiles?
Or is the perceptual/relative something they would handle on their end?
"Should I be embedding special profiles?"
They specifically state embedded ICC working space.
"They ask for sRGB files,"
No, they say either sRGB or Adobe RGB. https://prodpi.zendesk.com …0322071-File-Requirements And yes, the larger gamut of Adobe RGB would be better, although in this particular case the difference wouldn't be large because the yellow-orange-red part of the color spectrum is the area where Adobe RGB is only slightly bigger than sRGB (whereas the green-cyan-blue side is very much wider).
" Or is the perceptual/relative something they would handle on their end?"
Yes, that is something they set (and don't change) in their software, but the fact that they say to soft-proof for Rel Col would make me assume that that is what they use.

Which inkset are they using? Perhaps they are limited by a narrower gamut than might be possible using a different printer.
Although they may be using a high end inkjet for their Fine Art printing, the Fuji printing will not be ink-on-paper but rather be done in a Fuji Frontier machine which scans laser light across silver halide photo paper and then wet processes it.

In Lightroom Print module you can route the output to a jpeg file instead of a physical printer. Jpeg files are sRGB. When you do that you can try one with Perceptual conversion and another with Relative gamut conversion.
Conversions to working spaces (sRGB, Adobe RGB) are always Rel Col, no matter what you select, because they are matrix based and lack device-specific LUTs.
