No. You still do not get it. What matters is the size of the image in pixels. For 8" x 8" image and 300 ppi you need to start with a canvas size of 2400 x 2400 pix.
Upscaling the image is just equivalent to reducing the print definition and you do not get any better quality. It is another case of "What Goes In Comes Out"
Edit: You can leave the scaling to the printer. It will be as good as you scaling. 40 second example: Gimp 2.10.38 (linux)

Circumstances where you might need to scale yourself, is sending the image to a commercial printer. They might insist on 300 ppi (or close) In that case it is up to you to make the image as good as possible, using NoHalo interpolation to upscale, sharpen the image...etc
