Is there a standard that all DC power jacks follow? More specifically, I plan to use 5.5/2.1 mm barrel, and I've found a bunch of these components on eBay, but they all lack drawings (not to mention 3D models).
I've found a 3D model, but it does not fit to a footprint of one commercial component that I've managed to find. And that is why I'm asking for a standard.
For example, this component

does not have a drawing, they only state that it follows the IEC 60130-10 Standard, but I wasn't able to find drawings for this standard.

There is no standard footprint for a DC jack connector. There are too many variants of this connector out there. You can have round holes, SMD, slots, switched pin on the right or on the left.
As JRE commented, get the manufacturer's datasheet and use the recommended footprint.
If there is no footprint in that datasheet, next time buy from a higher quality manufacturer.
