One thing that irks me about GTK is that the file picker doesn't have thumbnail previews and I also find Qt to be too heavy for me. Can I have thumbnail previews with the FLTK file picker out of the box or would I have to modify FLTK to get that?

The key, as I'm sure you can imagine, is that robustly supporting thumbnail previews tends to be neither "fast" nor "light" so tends to be missing from lighter weight toolkits.

The fltk built-in chooser doesn't do thumbnails as a result (in common with gtk and so on) but it does provide an (optional) preview window for the selected file, which might help?

Failing that, the fltk built-in chooser is intended to be subclassed so you can extend it if you're feeling keen...

The FL_Native_File_Chooser, in contrast, basically attempts to load the system provided chooser and only falls back to the built-in chooser if that fails... But the chooser it loads from the system is usually gtk, so...
