Any advice on drilling/cutting 23cm diameter holes in a ceiling for ventilation fittings? Should I buy those 2-sharp-point-scraper-drill things or is it fine drilling lots of holes and then cutting through with a jigsaw? This is for in our new-built home so don't want to mess it up. I have 6 holes to drill. Thanks.

multitools are pretty sweet and will do the job easy peasy with the plunger blade attachement.

plus you will find them very handy for all sorts of things later on

If you end up trying to do it manually I have a suggestion.
I have had some success in the past in making holes for ducting vents and speakers in gib ceilings by cutting the paper on the gib first. Either just with a hobby knife, or on one occasion I mounted a hobby blade in an extended compass and used it as a scribe. That way tears don't migrate to the outside of the circle on the 'good' side of the gib.
