Panspermia does not require that asteroids/meteoroids were the

Again, what do you care if a few people want to explore this line of
investigation?

So what organic material have they found on them?

On meteorites? Well, nobody has identified an interstellar meteorite,
but meteorites and comets formed within our own solar system contain a
variety of organics- amines, amides, amino acids, carboxylic acids,
sugars, aromatic hydrocarbons, and others.

It remains a viable theory that the organics which allowed life on
Earth were seeded by material formed elsewhere in the Solar System.
