One possible improvement could be to do -v "$PWD:$PWD" -w "$PWD" to make paths work more as expected

Not sure I understand, Can you maybe share an example command that will act in an unexpected way?

If one would happen to use absolute host paths in arguments etc they won't work, ex:
docker run --rm -i -v "${PWD}":/pwd -w /pwd ghcr.io/jqlang/jq:latest -f $PWD/file.jq ...but even with the -v -w trick above paths outside host $PWD will not work... so not perfect either.

I think this is a slight difference no need to fix. -f accepts relative path, env.PWD is different, but should be ok.
