The tricky thing with Nostr is that it wasn't designed to recommend who to follow; That was done on purpose. But it's a feature that has been bolted on by some clients, perhaps due to Twitter nostalgia.

However, Nostr offers a clever trick: If you know of a npub, you can log into a Nostr client with that npub in read-only mode. If you like what you see, then you now have a list of people to follow.
