(written assuming you and the repeater are in the USA)
Also, repeaters (indeed, any station aside from telemetry) are only required to identify every 10 minutes during communication and at the end of communication. If a repeater hasn't had any usage in the past 10 minutes, it has no need to identify (though many are programmed to periodically do anyway).
I would go with repeater on pole in your case, and I would use some kind of mesh configuration. Different manufactures have different mesh options.
But since you are asking in hamradio section, maybe you would use AREDN mesh network https://www.arednmesh.org
