I'm not an expert on this topics, also, but as there are many kinds of vinyl and laminates, you should know that also each house won't need the same things, different builds would need different workarounds, as an house breaths and lives in concordance whitin its structure.
Anyway, I think that an acoustic or thermal isolant mat would be a nice add, as it also usually doesn't costs much (by comparison with the others parts). Thought that the pre-sealed boards have it already.
Those boards are also something I would look at, but not on the rooms where there are stoves; in there I will let the simplest tiles.
Consider also that many boards are MDF rather than wood, not the same thing but might do the job.
@pdurrant: sorry, I know that different Countries has them own culture and standards, I recall to have seen so many carpets/moquette in UK.... but I'm not sure during time how might fit the linoleum on bathrooms; I mean inside won't it keep mildews?
I am for "the lesser the better" on those topics..
