I'd say to try and decide how you want to intake, and then go from there. Coconut oil can be really easy to make, and quite effective, but is geared toward edibles and topical. I'd have to look for it, but I think there is a sticky post in one of the forums on an easy and effective recipe for coconut oil.
Smoking and/or vaporizing are better suited for oil/hash/wax/shatter type concentrates. Two of the easier methods to check out in my opinion would be QWISO or Rosin pressed oil. Rosin is probably the easiest to try, but can be difficult to master getting the temps just right (depending on equipment used). Bubble bucket type hash looks fairly easy as well, but the kits can be pretty pricey compared to some of the others that can frequently be done with stuff you may already have around the house if you're just looking to try things out. If you've got any trim lying about from a recent(ish) harvest, I've found it can be great for playing around with concentrates and edibles so there's not as much a feeling of "waste" if results aren't as desired.
