#27 is pretty red, but it would work, as TP Zelda does appear to have reddish hues in her hair in some artwork. I think #12 or #14 would be a better choice for you if you think a darker brown wig would look better on you.
Do you intend to modify your wig with extensions? If so, I would definitely recommend #12. It's really easy to find matching extensions for that color. The only extensions in #14 I've ever seen online are actually a much better match to #27.
I would avoid the Linda XXL, the layers will indeed make it difficult to braid and maintain.
