Iiuc, an A§RC holder based on any reason does can work as locals do, without a (open) work permit, when the person is a spouse of an ROC citizen. I think there is no description on the A§RC except for marriage based ARC, though.
An APRC holder who is not a spouse of an ROC citizens can work as locals or spouses of citizens do, by getting an open work permit.
If you get your APRC through work ARC and you are a spouse of a citizen, you don’t need an open work permit, because you have a work right as a spouse of a citizen. In case of a divorce after getting your APRC, you can work as same by getting an open work permit.
Imo, if you can get an APRC through work based ARC, there is not much reason to get it through marriage based ARC.
