I agree with all of this.
OP you've got lots of new suggestions here to look at and explore but my advice, FWIW, is that actually the more restrictions you have, ie. the more 'must haves' or mustn't haves, the easier it is to narrow down what will actually suit you.
It can sound pedestrian rather than the wild freedom of just "running away to the seaside" but the basics matter - transport, roads, airport if required, shopping, leisure facilities, GP, hospital, internet provision, the weather - windswept and lashing rain might sound dramatically romantic but for your forever it's probably just going to be bloody annoying.
Now you've got lots of place names and areas make your 'this is me' list and view everything through that filter.
TLDR: There are countless nice houses in nice places in the UK, being clear about your required framework will help guide your choices. Good luck.
