re: also which template were you referring to?

Well, you wrote this in the cMap support forum, so I supposed the cMap template. Really though, it does not matter, all templates will output the same categories because they all use the same code to do so.

re: if a change is made to it is it futureproofable?

No, not this change. If an update is released to a template with this change, the change will be lost and will need reapplied.

re: Another option could be to remove “show all categories” from the select menu. Is this possible.

You could use CSS to hide the hide it, I think, but chances are that when you add new categories you would have to adjust the CSS.
