The question about PCB Fabrication

I've now designed my very first PC board, and am in the process of reviewing it. One thing that occurred to me is that I created a couple of custom pads and wasn't paying attention to whether the hole sizes were standard drill sizes. It's no problem to go back and change them, but my question, is: Is there a set of standard drill sizes that should be used？V-score is so the boards can snap apart?

V-scoring allows boards to snap apart. They also do internal routing, which allowed you to make the boards on a panel with straight sides (the v-score) with rounded ends (internal routing).
Datasheets for many components include a suggested PCB footprint with drill sizes accounting for plating thickness.
