Any dripper that isn't designed for more than 2 coils should suit you just fine (if it has post holes arranged in a circular instead of linear fashion, it's probably meant for multiple coils).
My first dripper was one of these, a tiny little Trident clone. Small, single or dual coil, and super reliable. My girlfriend used these exclusively for a while, and I still use them for testing flavors, as it's very easy to center builds and wick.

I have a wider variety now, and I'm a big fan of my Plume Veil clone. It's nicer for dual coils, has considerably more airflow, but can be a bit on the leaky side. Very user-friendly, and has a nice mix of flavor and vapor. Easily the most capable of producing vapor, of what I'm listing. It also has a dodecahedron on it, which easily makes it my favorite atomizer (although it would be without that).

A nice, straightforward dripper would be a Magma, and here's the clone I own. It's collecting dust because it's not very airy, but that could make it nice for mouth-to-lung inhales, the conventional cigarette-style of vaping, which most people do at first, then transition to "direct to lung" when you get an atomizer that can accommodate it, like the Plume Veil. Oh, I should mention that the magma is top-notch as far as flavor goes, definitely the best I've listed.

Lots of people started on some kind of IGO, but I've never owned one. All of the above have adjustable airflow, which is nice. They're also very common drippers, classics, if you will. That means you can find plenty of build videos, or threads here on ECF. Well, the trident actually isn't in that category, it's just what got me started. Kinda common, probably more so in the past.
There are no shortage of RDAs, and as long as it's not too fancy (I'm looking at you, veritas), it should be perfectly good for a first time.
ETA: Oh, and congrats on being smoke free! Fantasizing about what kind of vape gear to buy next is definitely 70% of what kept me smoke-free for my first several weeks, puffing on my ego
