I would say explore, search for the books you’re interested in, look through the reviews section, see what opinions you resonate with, request their friendship if you like their profile and reading shelves. If you watch booktubers you can try to find their profile… most of my friends on Goodreads are people I don’t know, but who are very inspiring. After all, it shouldn’t even be such a stress, you’re there to monitor your reading and find more books “socially”✨🥹
