SVG-to-CMYK file Conversion

I have an SVG artwork that will be printed as a large sticker on an outdoor sign, and I need it converted to a press-ready CMYK file. My top priority is color fidelity: the final CMYK version should match the current on-screen colors as closely as possible while still being suitable for wide-format printing on weather-resistant vinyl.

Please preserve dimensions, transparency effects, gradients, and any vector details already in the artwork. I also want to avoid unexpected color shifts once the file reaches the printer, so include any embedded profiles or recommendations you feel are essential for outdoor vinyl output.

Deliverables I expect: the flattened or layered CMYK PDF (or AI/EPS if you prefer) ready to hand straight to the print shop, along with a quick soft proof so I can compare before sign-off.
