I am using GNOME 3.38.5 and the Adwaita theme.

Having dug into this a bit, the lighter text on the findbar appears to be part of the specification. We're supposed to be using a "text on light #2" colour, which is similar to the "Remember this decision" text in our panels. We similar use a "text on dark #2" for the dark theme. Closing this as INVALID.
