My first bug report, let me know if I need anything else. Thank you for your time. 

Aeon has a lot of the necessary packages for jxl images and is just missing the thumbnailer for Gnome Files. 
Please add jxl-thumbnailer to the default install.

3. sudo transaction-update pkg install jxl-thumbnailer
4. reboot, Open Gnome Files and check location of the .jxl file and the thumbnails are now shown. 
5. sudo transaction-update rollback # to undue the changes.
