It's not just limited, it is fairly misleading. I had to actively tell my devs to ignore the Inspect panel because it was giving them pixel values when we use rems, or they would hardcode colors that should have been design system tokens because Figma doesn't use color styles in things like effects. Lots of absolute values that should be relative or responsive or tied to tokens. There is a reason there are no good Figma to HTML/CSS plugins or tools out there.
