@zorroshadow Dont know what help you want from the forum or whether you just wanted to make people aware of the issues.
That Sky have offered to release you from contract means you have already registered a complaint about the install and Sky could not satisfy you. Installs do vary and in most cases the work is not done by Sky's own engineers but by Openreach or their sub-contractors who are often in a rush. All I can say your experience isn't typical most fibre installations are done neatly and professionally even if a second visit is required..
Full fibre is technically a far better system than the use of copper phone lines to deliver a good broadband service and has far higher reliability meaning it should be a superior system. Latency is normally slightly lower than over copper as there are fewer steps in the delivery. I certainly never heard of 60,000ms which is one minute being reported before so something is seriously wrong if that is what you are measuring. You other comments imply a serious issues with your home network..
Are you registered with Sky's Accessibility team https://www.skyaccessibility.sky? They are a small team who can often offer support to customers with additional needs. Ideally you need access to a local IT support service likely to be in the form of volunteers working with a local charity. In days gone by I managed advice centres and worked with colleagues in the voluntary sector to get the practical support our disabled clients needed.
You may find moving to a different ISP may help, as the very large companies like Sky and BT cannot always offer tg]he specialist support you may need. Smaller companies can offer a more flexible support service and the people you call are not answering queries about a huge range of services that Sky agents have to do. There can be a premium but given your need for the service it could be money well spent. Zen have a very good reputation.
Hope thst helps.
