There’s https://osm-boundaries.com, but it doesn’t really work (for me).

You should also be able to select elements via Overpass API, but it doesn’t work reliably for me at http://overpass-turbo.eu

This is the query for mainland Netherlands:
curl --remote-name --remote-header-name --location --max-redirs -1 "https://osm-boundaries.com/Download/Submit?db=osm20210531&osmIds=-2323309,-1216720&format=GeoJSON&srid=4326&simplify=1"

You also need an API key that depends on your OSM account. Result attached.
