Fully remote now. Relocate to where?

Hi there, throwaway account for anonymity. I just changed jobs and my new role is fully remote so I can go anywhere in Europe. I have a British passport and my wife is Irish, so visa wise we are fine.

My new salary is 275k with 300k in RSU’s yearly and I have some stock options, roughly 1-1.5m from previous jobs that will likely become liquid in the next 2-3 years.

I had been considering Andorra, Croatia, Malta, but am now also looking at Greece.

Advice needed please.
