Which type of local network organization (ADSL, Ethernet, Gpon) and equipment should be chosen?

Question

ADSL

I want to make a local network in a small village for exchanging files through a server (a small web interface), and another provider promised that he would give us a 10Mbps radio link if we organize a local network ourselves.
Distances from the server to computers are different, from 20m to 2km.
You need to choose the most budget option, since the project is non-commercial. I have not chosen a server yet, but I will choose a used one designed for small loads (there will be about 30-40 people connecting).
Considered 3 options.
1. ADSL switch for 48 connections and a telephone wire to each.
2. Via Ethernet. Divide all computers into sectors and use a Cat-5e cable from the server to each sector, and connect with a switch every 100m.
3. Spread optics with Gpon topology.
Perhaps there are other solutions, I will be happy to get acquainted with them if someone advises.
My knowledge of organizing a local network is not very large, and therefore I will not refuse references to literature, I like to read and learn on my own.

Answer 1

it’s logical to make the right directional wifi, it will probably come out 10 times cheaper than any of your options.
Well, as for the ethernet account, it will die so often due to static with an open broach that you won’t save up enough for equipment, it’s
stupid to take a boo server, it’s easier to assemble a new one on cheap hardware, usually everything fits into 20 thousand, or even cheaper.

Answer 2

Few initial data
The best route is optics, and where up to 100m - twisted pair

Answer 3

If you are building a wireless infrastructure, then pay attention to TP-Link TL-WA7510N, a budget solution. Powered via PoE, all-weather rugged housing, operates at 5 GHz, can operate in repeater mode.

Answer 4

I repeat what I wrote in the comments for opium
Wi-Fi is not a 100% option, this is a village and it is densely planted with trees, there is no direct line of sight anywhere. If it were possible to cut out windows, then everything could be built on Ubiquiti or MikroTik, they have a lot of ready-made solutions.

Answer 5

PS It's kind of sad that no one on the toaster understands network technologies?
