Looking for tips and advice on training models of large vehicles

I want to train two specific models, Loras most likely (but happy to take the community's advice on other options) on very large vehicles:

• The HAV Airlander 10 airship
• The Royal Navy's HMS Queen Elizabeth II aircraft carrier

People who have experience training vehicle models, what is your advice? Is it possible to train a model that understands something as large scale so I can then prompt "a view of [the vehicle] sailing in the North Atlantic" and "an old sea captain in full uniform, standing on the deck of [the vehicle]"? Or does it make more sense to train separate models for wider views and closeups?

Thanks for all your advice!
