Welcome.
Introduction to common vaping lingo....
VAPE LINGO | The Vapor Hut (NOTE: Some of these definitions are a bit outdated, such as mods which more often than not are box mods rather than tubes these days, but overall you'll get the idea)
As for suggestions, I would say start with a decent 30W-50W mod and a retail tank such as the Aspire Nautilus. A decent 30W-50W mod will work with a very large variety of tanks and dripping atomizers, and the Nautilus is a good tank to start with because it has great flavor, really good vapor production, and is easy to use. You'll save a LOT of money by skipping the early steps a lot of us have gone through with "beginner" level "kits" and start out with a setup that most moderately experienced people now use. From the Nautilus you can decide if that's plenty for you or if you want something a bit different it will give you a good idea where to go next with your tank needs. Rebuildables, subohm, or something else. Many will find the Nautilus itself as more than adequate and will never feel the need to move on, but if you do eventually find it unsatisfying then you'll have a really good idea of where to go next.
A LOT of people will recommend a subohm tank as a starter tank. I don't believe this is good advice for beginners because they cost more to use and consume a LOT more liquid during use. The added expense can add up quick, and a beginner doesn't even know if they will like subohming. The other aspect of subohm tanks is that they work best with straight lung hits which is not how most people who smoke are used to doing things. Most people are used to drawing into the mouth first and then inhaling, known as mouth to lung hits. If you're not comfortable with straight lung hits and prefer the mouth to lung method then a subohm tank is not going to make you happy. The Nautilus on the other hand works great with mouth to lung, and although it's restrictive, it can be adjusted to what I would call beginner level straight lung hitting.
Anyways, that would be my suggestion. 30W to 50W regulated mod and a Nautilus (Or Nautilus Mini if you don't like the big tank size). That's a great place to start and will save you a ton of money on the normal upgrade path that most of us have taken. It's what I would consider starting with a good mid-range setup. Much better and more satisfying gear than beginner kits, but without the expense and hassle of the really advanced gear that rebuilders and subohmers get into.
