As far as I know RGB and CMYK are just the different colour ranges of a PC screen and a printer. If you save an image in rbg and send it to a printhouse the printer will convert it to cmyk while printing automatically.
The reason that the image is dark is not the colour range, but the fact that you work with an LCD/FTF screen? They are mostly not in true colours and more so a lot of brighter than an old rct would be.
If you work on a pc digitally, keep in mind that your image will be darker afterwards, the new screens are brighter just through their techniques.
When I noticed it first I begun to alter my allready finished images with PS to make them brighter and it went well. But that have its limits.
I have to clear that up. I have worked in a printing house for some time and we had such stuff in my studys as well.
If you create an image in CMYK on your PC, and get it to print it might happen that your product looks different.
Images should be created in RGB on a screen. How much a image will be printed don't alter the prefered colour profile.
Important are:
use the RGB profile the printing house want to see, in Europe mostly sRGB IEC61966-2.1, be aware of the bleeding you might have, means the cut the printing house have to calculate.
Inform yourself on which kind of paper you want to print, what they offer, and what kind of printer they have.
Your document size is not a reason for another colour profile, your desired printing device is. In most cases using RGB is completely ok, because the printer convert it for themself. For professionall printing or at home, doesn't matter.
Hope that helps.

If you're printing on a regular printer RGB works perfectly, and the only thing to remember is to print out a test first then adjust your images accordingly.
CMYK is used for large scale printing. meaning both size and number. Yes, if you print 5000 business cards you might be using CMYK or if you're printing a huge banner - same thing.
