[@The Harbinger of Ferocity] Good points all around. I agree with the majority  (although I am a bit of a fan of high fantasy). As for class, I was also considering the Hexblade warlock, but I'm going to take a look at the Akashic classes Ermine made. Some of them look quite interesting. If I don’t do one of those and warlock is taken, I may try either one of the new UA sorcerers or the UA druids, depending on need.

In short, I'm flexible.

For new players, I personally recommend classes that do not have a large number of options for each round, at least for the beginning. These "simpler" classes would include Assassin rogue (positioning keeps this class fresh), Battle Maater Fighter (extremely fun to play, and gets more complex over time as you learn), Barbarian (both archetypes - smashing good fun), Champion Fighter (possibly the simplest archetype overall, but very powerful), or maybe a warlock if you want some simple spellcasting. If you are unsure of your abilities, I would avoid any class that prepares magic instead of learning a specific number of spells (can simply get overwhelming), or any class with a large variety of options like bard or beast master ranger. That is not to discourage people from playing those classes; just bear in mind that they are more complicated and will likely need a lot more frequent questions.
