The union of st_overlaps and st_within yielded the desired results for 2000 and 2010 zctas. For some reason this didn't work for 2020 zctas -- zctas that only share a boundary with the county were still present. I couldn't figure out why and couldn't figure out a different predicate that worked, so I manually removed them. I'm thinking it's some nuance with the 2020 geometries themselves.
