Congrats on starting your homebrew adventures!
German-style pilsners are great (some of my favorite to brew), but...I would not recommend this as a first beer, because they can be challenging to ferment when you are still learning the process, if you want to have a super traditional result. Specifically, the better pilsners require pretty good temperature control (keeping it below 55 degrees ideally), and aren't very forgiving if something goes sideways. There are pseudo-lager possibilities -- e.g., using Lutra as your yeast -- that might be an OK fit for you. Northern Brewer has an extract kit called "Legend of Lutra" that might fit your needs, although I haven't brewed it myself. (as an editorial aside, Lutra does ferment pretty cleanly, *but* I wouldn't say it is necessarily lager-clean for flavor profile...although it can get close)
I would also second the advice from neuse -- extract brewing is a good mode for your first few batches, and then you can modify if you choose after that.
