Will my way of grounding a twisted pair cable with a shield (FTP) work?

Good day
I have a dilemma related to the Internet network in a free-standing building. It's about grounding the shielded network cables.

I have (unfortunately) used FTP cables (the marking on the cable is U/FTP - shielded are 2x4 wires + there is a thin bare metal wire going next to the foil). I'm trying to figure out how to ground it now in a simple way to make it work but without using shielded sockets and grounding through devices.

Although I can use a crossover knife, I'm a layman - I've already started doing this network myself and want to finish it myself - mainly for financial reasons. Let's leave aside questions of competence.

I plan to:
a) in the rooms use ordinary sockets without shielding and connect to the devices already UTP cables without shielding.
b) in the box where all the cables come together use a strip with RJ45 sockets also without shielding and there also connect to the devices already with UTP cables.
c) ground the shields on one side, in this box - but before the RJ45 sockets on the strip - that is, somehow gather together those bare steel wires that go along the shielding foil or use metal clamps on the foil (before the sockets in the RJ45 strip) and bundle this together to ground.
d) connect this grounding somewhere

Questions:
1. Is the idea of not using metal sockets and plugs that carry the shielding to the devices, and instead grounding the wires separately valid ?(I know it's unprofessional but will it work well)
2. Is it correct to ground the FTP wires on one side?
3. what to connect the grounding to ? - Dig something into the ground (I read something about metal buckets filled with sand and salt), or maybe to the grounding of the electrical network - yellow wires in the outlets? (I have some copper rod buried in the ground, but I don't know if some current is not induced on these wires because the electrical network quite convoluted although installed by a professional electrician, of course - I can measure I guess.

I would be very grateful for an answer from someone expert in matters of stray electrons.

1. simply do not ground. The wire will behave like U-UTP.
2. If you really want to ground, only on one side. You use FTP panels or, better yet, shielded keystones. You connect the panel to the Main Grounding Bus with LgY4mm2 wire. If the electrician didn't do the GSU then chase him.
3. There are solutions with grounding on two sides, but it's a bit complicated because of the equalizing currents and at home it's like hunting a fly with a Kalach.

@konik666 thanks for your reply

I've read that if you don't ground the FTP and the network cables go together with the electrical ones, it makes some kind of "antenna" out of this foil - that's why I'm so hung up on this grounding. Honestly, when ordering shielded cables I had no idea that it was still grounded - I thought it was some kind of shielding - let's keep quiet about it. I mainly want the cables (they are 6 cat) to work well with the disk array 10Gbit and that the transfer does not drop e.g. with a running vacuum cleaner.

as to your answers, I have a doubt about point 2:
1. maybe I really do not ground at the beginning and if there are problems with the transfer (I can measure it), then I'll deal with it.
2. if, however, ground it, then thanks for the hint with the panel - probably will not be much more expensive and it will save the combination. the only question is whether this wire 4mm2 not too thick? - can't I use the yellow cable 2mm2 from the electrical wire that I already have supplied? all the yellow wires from the pins meet on a small strip in the distribution box and this is connected to something dug into the ground with such a 4mm2 wire as you write. I will find out if this is the mentioned GSU.
3. from two sides I would not want to ground - much simpler from one so if this is a sufficient solution - this is how I would do it.

If the wires are run very close to electrical (10 cm and less) and you still want to have 10Gbps then it would be a good idea to do this grounding.
This 2.5mm2 wire you can not use - in addition to grounding, it serves as a wire that carries away higher harmonic currents (such as from filters in switching power supplies). You would only make yourself worse.
4mm2 is the minimum for a couple of reasons (I will not elaborate). I had cases that you had to run 35mm2.
GSU I see you do not have. According to the current art of construction, there should be a cooper e.g. in the boiler room and to it all grounding (furnace, hydro, surge arresters, switchgear ...).
For 10Gbsp necessarily good brand keystones at the ends. The cable is not Chinese or other supposedly branded "Madex”?

It's a centuries-old building so GSW, grounding for foundation reinforcement, etc. is unfortunately not there. But something can always be done. Next year I'll be digging up and insulating the foundations and on this occasion I may even make an abutment grounding - I'll get interested in the subject. The new plumbing and central heating system are of non-conductive materials so I'll probably let the topic of GSW go (although there is an old well hydrometer used for watering the lawn).
What about the LAN is the wires go in places right next to the electrical so probably grounding will be needed. That is, I will have to dig something in - maybe best to hire a professional. We'll see what comes out of the wiring tests with some vacuum cleaner or washing machine fired up.
The wires are from Draka, designation UC400 S23 Cat.6 U/FTP LSHF - foiling has 2x4 conductors.
Thanks for the advice.

1.Drak wires - ok
2. Good grounding - the basis for the proper operation of surge protection.
3. GSU is just needed when the water system is made with plastic pipes. Metal pipes formed natural grounding. Now a potential can accidentally appear on metal components (such as a boiler). In hospitals and service stations, you need to ground even taps, baths, radiators and window frames.
4. Temporarily connect shields to this bus in the switchboard, and in the future as you have the opportunity think about comprehensive grounding / equipotentialization.
