My opinion may be contradictory.
Many great suggestions and responses here. Your timing of buying your first pin is terrible. No offense but prices are the highest they have ever been and the supply chain is slow. That being said, the resale market is great if you get something you don’t like.
I was never into pins but my 9yr old is infatuated with Stranger Things and I decided to buy my first pin for Christmas. Not sure if it was a blessing or a curse. Im now obsessed. 10 months in, I own a Stranger Things, Jurassic Park, Simpsons Pinball Party, GnR and a few more on my wishlist. I never tried a single pin before I bought them. Wish I did for Simpsons.
As a noob, which you are not, I recommend buying a pin that has a theme your interested in. You will enjoy playing it regardless of what the experienced guys have to say about a deep ruleset etc.
I don’t care how much a game like Iron Maiden plays (no offense to IMDN owners) I wouldn’t want to play a game that’s constantly playing music I’m not into.
If there are a couple themes tour interested in, go try them out. If they are not in a local public area, look for members that have it in their collection. If there is one thing I learned this year… the pinball community is incredible. We have like minds and completely different background. Most would welcome you into their hole to try a game your thinking of.
Goodluck and happy shopping.
