If you currently live in England and want to leave, but can't find a route to settle in Europe, my suggestion would be Scotland. It's a massive oversimplification, but on balance I'd say it's a better place to live if you're on a low to middle income. England is probably a better place to live if you're on a high income, because the highs are higher (in London, for example).
I've lived in both countries for many years, and in my experience the quality of life is much higher in Scotland, generally speaking. Prescriptions, dental care (for under 26s), university tuition, water, and bus travel (for under 22s) are all free at the point of use. Dental care is also to be extended to all ages in the medium term. All of those are usually chargeable in England. This being a rail forum, I'd also say that the railway is better supported there, and infrastructure spending more consistent (the total decarbonisation of the entire railway by 2035 being a key example). There is less of the decay you find in neglected parts of England.
On the cultural point, I think Scotland is a better match for you too. Every single area in Scotland voted remain and its politics are broadly progressive, and will be for the foreseeable future. You'll find that the Conservatives up there are also much more moderate than down south. It's very far from perfect, but I suspect you'll find more to align with there than down here.
If you're set on leaving the UK, I think it's worth remembering that for all its faults, there aren't actually very many countries out there that will provide both a) a similar or better standard of living; and b) the kind of tolerant, liberal society you're looking for. On almost all measures, places like Norway and Sweden tend to come out on top, but unfortunately you'll find them amongst the harder places to move to.
