Does this monitor have built-in speakers?

Yes. However, they are of low quality.

Will this monitor work on a PC without a graphics card? Or is it necessary to have a graphics card for it to work properly?

This depends on the capabilities of your onboard graphics card. If the specs line up with the resolution of the monitor then it will work. If not, then you will be presented with messages from the monitor stating "out of bounds from the input source". I suggest looking at your system to identify the graphics specifications and match your purchase based on that.

Does this come with a display port cable?

Yes, mine came with a single display port cable.

Does this have PIP and PBP mode and is it a low blue light monitor? Their website doesn't give complete specs for some reason.

The manual claims there is PIP/PBP (page 30). It also claims a low blue light setting (page 20).
