Depending on your Calibre settings (Preferences > Behaviour > Yes/No columns have three values), there's two types of bool columns. The tristate one has a blank undefined value, which is the default. The setting affects all libraries though.

If you'd rather not use tristate bools or want more options, you might want to look at a 'text, but with a fixed set of permitted values' column type. This makes a dropdown list. Check the tooltip for "show checkmarks" (if it's available in 4.23).

EDIT: bools - booleans, yes/no columns
