Answer 1

yes, everything is just access groups on a folder or, ban everyone and give only to those who need it

Answer 2

Don't forget, there are permissions at the file system level, and there are permissions at the network share level. It is necessary to rule there and there.
If you allowed at the FS level, but forgot to allow access in the ball itself, then of course nothing will work.
