The three most sophisticated scents have been discontinued.
Jean Patou Pour Homme, Versailles PH and Dunhill '34 (the latter supposedly given to 007 by Ian Fleming to be his 'signature ' scent. You'll know why when you smell it)
So they're hard to track down, but not impossible.
Antaeus has been advertised as 'suitable for romantic wear' and so it is, but it also makes a helluva 'suit and tie' scent. It's quite elegant.
Creed's Original Vetiver also fits your requirements; as does Versace L'Homme, Trumper's Eucris, and Chanel's Egoiste.
These are completely different smells, but they'll do splendidly for a night at the opera or a luncheon at the yatch club. So, the good news is there's plenty of choice.
Unless this business meeting carries a threat of hostility; if so, then go to Vintage Tabarome by Creed--- an favorite of both Winston Churchill and Humphrey Bogart----No one will mess with you . . .
Having said all this, you have to find a scent that fits your personality, of course.
Do not take my word or anyone else's.
If you can obtain decants or minis to sample before purchasing, a full bottle, that's the smart way to go about it.
It would be a good idea to read the reviews section, for a good contrast of opinions regarding these subtle yet powerhouse scents.
However, ultimately it's up to your nose. You'll be the one wearing it.
