Howdy jerok, & welcome!
You might try simply a classic EDC, to see the early point of the world of scents.
Roger and Gallet Extra Vielle (Jean Marie Farina) is a good choice, so is Aqua di Parma. And for one with a bit "extra", try Dior's Eau Sauvage. These are all citrus, but really classy and have stood the test of time.
The world of chypres and fougeres is huge. Armani original is a great citrus-fougere. If you like Guerlain Vetiver, try Encre Noir by Lalique. And how about a woody scent, e.g., DSquared He Wood.
And check out incense, eg. Comme des Garcons' line.
Oh, the places you'll go...
