Macbook Security

Is there anything I can do to have "moderate" security on my macbook pro? I love my apple products, for the most part, but their security baffles me.

I can completely disable security, and have my macbook log in with no password. Completely and utterly unprotected. And I can turn on security, which requires a password on rebooting, but can otherwise use my Apple ecosystem to unlock it (apple watch, etc).

Why can't I choose a middle ground? Why can't I say "apple watch only, even after a reboot"? It is so weird to me that they dictate either complete security, or zero security.

Any hacks or tricks I can use to get around this... design decision?
