European languages are all pretty connected, in the scheme of things, and have much more in common with each other than you'd expect at first or second glance. That said, Spanish seems a safe bet, as per tfa. Coupled with the fact that so many people speak it, you could certainly do worse. I'm currently learning it, with the help of some lion's mane, and it does feel like a worthy pursuit. If I had to guess at a real answer to your interesting question though, I'd have to guess Russian. They've had a ridiculous amount of high-quality thought and literature, relative to their resources and population size.
