If you shoot in RAW format only, you can ignore setting the color space in camera, that only apply on jpg or tiff file format create by the cameras.
when you process your RAW files in Lightroom or Photoshop, you only set color space when you export your images to tiff or jpg.
you can export tiff files in adobeRGB if you need to rework them in Photoshop, but you need select a color space that suits your final usage when export your final output
if you upload your image for online sharing, use sRGB only.
if you send your images for lab printing, use sRGB only,
for other types of printing, check with your printers what is the color space and type of file format they accept.
you use adobeRGB color on your final output only by specific request.
btw, I export all my tiff in AdobeRGB as I need to rework them in photoshop
I export jpg in AdobeRGB for stock photo submission.
I export jpg in sRGB for any other usage.
