To my knowledge, "imperfect" is used for languages that view it as more tense-y, while "(past) imperfective" is used for languages that have an imperfective aspect fully distinct from tense.
The perfective aspect and imperfective aspect, like other aspects, tell something about how an action or event is laid out in time: the use of the perfective denotes an action as a whole, with focus on the fact it's completed or the effect it has/had, while the imperfective focusses on the action's internal lay-out or the fact that it is or was ongoing. Like with many grammatical terms, especially those for aspect and mood, there's a lot of overlap, and what exactly a term denotes depends on the language. I don't think there's many languages that have indepently and/or opposing "imperfective" and "continuous" or "progressive" aspects, though a continuous or progressive aspect could exists apart from a more general imperfective (I'm not sure whether any natlang has this though). Also note that "imperfective aspects" is a category, there's not just "the" imperfective, though a language may only have a single imperfective as its sole imperfective aspect.
So, tl;dr I wouldn't worry to much about grammatical labels inter-linguistically, and pick labels for a conlang based on what you think is close enough, or usable enough, to how a label is used in other (nat)languages.
