How to export just a part of an existing and huge wordpress site to staging?

I have a WordPress site that has 13GB of content (I tried to export it using plugins), and I need to change its theme.

I just want to migrate some existing content, like, just last month, to localhost so I can test some themes on it.

Is there a way where I can do this?

I already tried to use Import/Export features from WordPress, but there I can just migrate Posts and Authors, and I wish I could migrate the existing plugins and their configurations as well, for example.
