Out of the Blue

I've been contemplating getting a hardware key for added online account security. This seems like a question that can take advantage of the high level of technical proficiency here (flattery is always a good run-up to asking a favor). Anybody have any advice to share? I have USB C on both my PC and phone, so that's probably the only interface I would need. I'm basically hoping to maximize security while minimizing effort. The best of both worlds doesn't seem like too much to ask. So, should I just get a Yubikey and call it a day, or is there more to it than that? Any wisdom on the topic is welcome. Thanks!
