It depends, as many have already stated.
If only one tool I would say TSC55 with a 800mm and a holy 1400mm tracks (crosscut and sheets) since it has the dust bag integrated.
If a package deal is an ok answer, then I would push a CT vac and an ETS sander. The sander is not special without the dust extraction, so can't recommend it as the only tool.
And ofc. the answer would heavily depend on his existing tools and projects e.g. would a Domino be a better fit with the vacuum or not.
