I can't find designs on Figma for what the box is supposed to look like checked. @atul, do you have any? If not, we should really talk to Ted about this... the placeholder text color was also missing, and all-in-all this amounts to designs that were not sufficiently fleshed out before being handed off to eng.

Given he's out right now, we'll have to make a call on our own. My view is that the margin should be increased (so decrease height / width), and the borderRadius should be adjusted to match the ratio of enumCheckBoxFill to enumCheckBox size.

Can you show me what height: 20, width: 20, borderRadius: 2.1875 looks like?

This color looks too dark in light mode in my opinion... it's kind of distracting. It seems like we have two light mode issues now: panelSecondaryForegroundBorder and panelForegroundSecondaryLabel, right? We should probably create a separate task under DES-71 for @ted to concretely investigate those colors and see can simply be updated to more appropriate values without degrading the experience wherever else they're being used today.
