To learn from a spirit, you must already have known how to connect with a spirit, meaning that you would have already known the magic that you're trying to learn.
Still, perhaps put the intention out there and you'll meet one, then you'll know how to summon one because you would have already met.
Fairies can be Seelie, but they're mostly weird and that weirdness can be dangerous.
I'd suggest that you pray to angels instead, whether that's with all the bells and whistles of the Rite of Abramelin and Lesser/Greater Banishing/Invoking Ritual of the Pentagram or simply a more Pentecostal expectation of angelic holy spirit work.
But seriously, though, they've never been human (except Michael, in some denominations) so their missing something "in translation" can be a hassle.
