Environment definition adds vertical space above
I already have found the solution to define a new environment without the additional space above the paragraph. But why does the "vanilla" way of defining this not work?

As explained in When should we use begin{center} instead of centering? begin{center}...end{center} is implemented via a list (trivlist) and causes vertical space before and after the centred text. centering on the other hand will not add additional vertical space.
That means that your asdf environment gets the 'usual' vertical spacing of a display environment, while goodgood just gets the spacing one gets when moving on to the next paragraph (due to the par).
You don't need the ignorespaces at the beginning of goodgood: ignorespacespar is the same as par as David Carlisle pointed out in the comments. Since the environment ends with a par I also don't think the ignorespacesafterend is required.

To add some evenly divided space above and below, is it good practice to simply addvspace{2.0ex}at the beginning and end? Like this: ->newenvironment{specialnote}{vspace{2ex}parcenteringbegin{minipage}{0.8linewidth}smallsffamily}{end{minipage}parvspace{2ex}}(You switchedasdfandgoodgood, btw.)

@henry Thanks for catching the name confusion (I hope the edit fixed it). I'm not sure about best practices withvspace. I'd have thought it would be more natural to usetrivlistor alist, but I'm not sure what one would have to do to get what you wanted then. Maybe you should ask a new question about that.
