So, so, many choices.

Dahl is a surprisingly good choice. He was an ethnic Norwegian
(possibly explaining his deadpan sense of humour) from Cardiff, Wales,
by the way.[1] Perhaps you have a weakness, as I do, for
English-language writers with foreign-language backgrounds, in which
case Vladimir Nabokov and (especially) Joseph Conrad might also be your
cup of tea and could not be bettered as a model for English prose. Try
Conrad's _Lord Jim_. Although written in 1899-1900, its language still
seems very fresh and modern, to my (admittedly pedantic) ear.

Getting back to works by native (and contemporary) speakers of English,
try non-fiction author John McPhee, e.g., a collection of three long essays
collected in a single volume as _The Control of Nature_. The individual
pieces can still be read online at https://www.newyorker.com/ , for
free, and the quiet effectiveness of McPhee's descriptive writing style
will knock your socks off.

I won't do it often.)
