I wonder if tiny bits of solidified glue (plus paper, wood fibers, etc) in the environment are much better than tiny bits of plastic?

Yes. Nature has evolved ways to dispose of those (unless it’s a synthetic glue that doesn’t decompose)

What characterizes a "synthetic" glue, chemically?

Don't glues generally involve polymers, like plastics?
