Make the holes no larger than necessary if you're concerned. 3/4" is
large enough for everything except the flex conduit. Electrician's
like to drill larger holes as it makes it easier to pull the wire.
Offset the holes a little bit so they don't line up down the middle of
the stud. Other than that - don't worry about it.
