The first ships that come to mind are the free use civilian tech transports: The Pelican, Grouse, Albatross, and Heron. These are usable by every non-Gallic non-Nomad ID in the game, but have in some cases extremely restricted sellpoints. (Edit: Technically also the Gull, although since it is strictly worse than the Grouse in literally every measurable way it currently might as well not be sold at all)
I would put them on every civilian house shipyard - Baltimore, Yukawa, Alster, Scarborough - and a selection of neutrals, maybe Freeports 1, 6, 8, 10, 11, Noshima, Bristol Bay.
