re: Fingerpicking

There are a few things to consider in a fingerstyle guitar. As auggie mentioned, a wider nut (usually at least 1.75") is considered preferable as is a more balanced tone. For these two reasons, many fingerstyle players gravitate to the OM style guitars, which have both of these characteristics. OM guitars are smaller bodies than dreadnoughts which generally cause the bass strings to be more muted and thus treble strings to stand out a little more. Some say smaller body styles project more, but I don't know if that's true. Also, in my experience, fingerstyle uses more barre chords and shapes up the neck to utilize voicings for the picked strings, so a lower action is also desirable. 000 size guitars are similar to OMs but with a shorter scale length if that would be something you prefer. Fretshack can certainly opine better about if any of this is true or not.

You'll also have to consider whether you'll want electronics in the guitar. Good electronics make a huge difference for fingerpickers. I know Maton has an excellent electronic system but any of the top brands will have that if you're looking to perform.

For the right hand, you have a few options. One is to develop serious calluses on your fingers (the route guys like Tommy Emmanuel and Joe Robinson have taken); learn how to use and maintain fake press on nails; or play a nylon string guitar, which is what Chet Atkins and Jerry Reed ended up doing.
