I don’t think you should try to combine PARA and JD, for exactly this reason. 
They’re different ideas with a fundamentally different structure. What Tiago splits at his top level - the PARA in PARA - I distribute throughout the system.
- Projects: as you’ve identified, sometimes our terms line up here but sometimes they don’t. There are many things that he might call a Project that for me are just an ID.
- Areas: he’s got his at the top level, mine are the first level.
- Resources: are just ‘a thing’ in JD world, distributed throughout your system and therefore organised by Category.
- Archive: similarly. I just let things stay where they are once they’re past their useful life.
Honestly I’ve never seen the appeal of PARA. It doesn’t seem to … do much?
