If you use “System Settings,” and navigate to /opt/homebrew/Cellar..../bin, you’ll discover that python3.XX is greyed out, and you can’t select it.

Keep “System Settings” open to the Full Disk Acess page (tab?), and open a Finder window. Navigate back down that directory tree (Cmd-Shift-G is your friend here.) Drag and drop python3.XX to the Full Disk Access picker, and Python will be added.
