Share permissions are only set for the share it self, not the folder. e.g. as soon as a user is authenticated NTFS permissions takes over. Normally Shares are simply shared with Everyone Full permissions and then usage and access is then controlled by NTFS permissions.

Let's just get something straight here... CAT is by no means anything to consider on the hardware aspect. It is simply a cable standard. Cabels created with CAT5e is minimum requirement for Gigabit ethernet up to 100m.
The only exception you have to running higher than CAT5e is if you have a lot of interference in your environment (or if you are capable at running higher that 1Gbps).
 
A good example for a simple switch to expand your network is this:

Go Unifi all the way for ease of configuration and sweet functionality.
This is my home setup:

 
I run my controller as a docker on my Unraid server.
All you do is define your networks and wireless networks and you are good to go


 
If you run multiple AccessPoints on the system you get awesome roaming and stuff
I run a USG, USW with PoE and an UAP-AC-PRO. The USG max out at around 500Mbps so go for the PRO if you need more than that.

If you go shielded installation you must go all in on it.
If shielding in any way is broken somewhere in your installation you will get feedback noise on your cables caused by differentiated grounding in your equipment. If you want to shield your cables, run them through a galvanized pipe.
