Now that Brexit is done, how does a UK citizen go about moving permanently to a country within the EU?

Just that really.

Can anyone explain the new rules to me?

I feel like England is almost the last place in Europe I'd like to live in so what do I need to do/provide to go and live elsewhere?

A work permit and a residence permit? How you get either depends on the country you want to move to
