Capital One Quicksilver for Beginners

Im 19, have no credit history, but am looking to start building credit. I see everywhere that the discover IT and Chase Freedom unlimited are the “best beginner cards” but I’ve been denied from both. I’m pre-approved for the Capital One quicksilver, and am wondering if I should open one.

I have 0 monthly expenses, make a decent salary, and am not planning on even buying much with this card- just need to start building credit.

Thoughts?
