I use Sai and have gotten prints made, but now I want to make posters, and Sai as far as I know is only RGB. What are my options and if you're experienced with this: is it better to convert? Are there other options for CMYK software? I need some knowledge.
SAI is old news. I recommend clip studio paint.

do you have an industrial printer and are you operating it all by yourself? otherwise, just use sRGB

These days getting prints done is more about altering your values for optimum print than fucking about with DPI or colour modes.
I wouldn't worry about it.
