In my eyes, also JLPT-wise, also depending on your goal (what you want to achieve), you don’t really need to finish Level 10 before finishing JLPT N5.

For more items to study, non-textbook approach, I suggest Core 10k breakdown, if you can tolerate Anki. If you can’t tolerate Anki, you might try this export here.
