Sorry for the delayed response. I mostly use Tamiya X prefix acrylic paint and these Badger paints:
Stynlrez primer (black, white, gray) -- The brand means it's made for styrene, vinyl and resin surfaces.
Model Flex, Minitaire
I also have a stash of long-out-of-production model railroad water-solubles such as Polly Scale.
I use the water-soluble term to describe what probably are acrylics (but don't always have that description on the label) that can be thinned with water. Other generic names are water base and water cleanup. However, for Tamiya I use their X-20A for thinning. For Badger and others I use this home-brew thinner formula: 6 oz. distilled water, 4 oz. universal acrylic thinner, 0.75 oz. retarder and 2 drops of Kodak Photo-Flo. However, when I use up my current brew I'll probably use Vallejo Airbrush Thinner 71.161.
For airbrush cleaning, I use tap water followed with Badger Spray-Thru Airbrush Cleaner.
