all depends on size of plugs, what you get used to using for stuff like thru drilling
thru drilling I like 5/32 but also have lots of 1/8 bits and a couple 3/16
eyes drilled with forstner I have 1/4 , 3/8 , 1/2 , and 3/4
belly grommets, I use what fits the swivel I need to reach the wire, as small as possible usually. generally 1/4 to 3/8 and inbetween
those step drills are nice for setting the grommets down a touch so they sit flat.
