While I can appreciate it on the level of nerd aesthetics, I would be dubious of the choice of Quenya. Unless you’re already a polyglot (as a demonstration of your aptitude for language-learning), it seems unlikely—without a community of speakers to immerse yourself in—that you’ll reach the kind of fluid fluency that would make it natural to think in a conlang.
And if you do in fact have the capacity to acquire a language to that degree of fluency so easily, but don’t already have several of the major world languages, it seems to me that the benefits of being able to communicate with an additional fraction of the world’s population would outweigh those of knowing a language selected for mostly no-one else knowing it.
