@Naphthalene do you mean this one?
Resources after N3 - #17 by Myria
In general, I think it is best to have a look at the resources oneself and see which books „feel right“. I had different plans but I was for example just unable to see myself studying Shin Kanzen Master although it is considered a very good series, especially after N3 where there are fewer resources available.
During N3, you can do AIATIJ or Tobira - I have and like them both. Although I find the grammar explanations a little bit short sometimes?
For JLPT specific grammar I like the Try! series because it feels more lightweight and easy to get through.
Sou Matome is a nice overview summary for grammar - favorite book to work through with my teacher because the book is so nice and non scary. But definitely not enough on it‘s own because there are hardly any explanations.
If you are looking for grammar explanations, have you had a look at either Shin Kanzen Master (not sure how good the grammar explanations really are) or the often recommended Dictionary of Basic Grammar and the Intermediate version? You could follow a textbook and look up details in the dictionary.
