I think you may be right that floor spring door closers (e.g. Geze TS500 NV) would probably be the best option for your double action doors. The only other possibility is a concealed closer (e.g. The Geze Boxer) fitted into the head of the door, but you’d need to check there was enough thickness & depth of wood there to fit it. It also need to be fitted professionally, so it may not work out much less expensive.
