In any case, the fastest trees generally also have problems. For
example, eucalyptus are very fast; but many are also very messy.
Poplars and their family are fast; they also tend to be shallow-rooted,
having surface roots with suckers that can create a thicket.

Ash trees grow quickly. As with gingkos and asparagus, there are female
and male ash trees. Female ash trees produce bucketsful of seed every
year, leading to many, many seedlings all over your garden. Male ash
trees produce pollen to which many people are allergic. Both have
surface roots.

Doesn't matter about what climate (a request for location had already
been requested upthread), because none of those trees you mentioned
make good privacy screens, in fact all being deciduous

Eucalypts are NOT deciduous.

Except for those that are not. let us do a billy?

"Nearly all eucalypts are evergreen but some tropical species lose
their leaves at the end of the dry season."
