Not a 'reading journal', but I track my reading in a physical notebook as well as digitally. In my notebook:

• List of books read each year, bubbles to color-code the book format
• Monthly page listing all books started; X through the bubble to indicate if I DNFed; bubble filled in to indicate it was finished that month. If a book rolls over to the next month, I leave it unfilled but outlined in the book format color
• DNF list by month; also color-coded

I do my more detailed tracking in Notion (author, audio hours, author representation, etc), Goodreads (mark 'read' and add to recommendation tags, and Storygraph (ratings).
