I've lived where you live, lived in a lot of tax friendly nations (cough).
I am tired of the lack of culture, OR intellect... (being brutally honest, it gets tiresome).
Did consider returning to the carib, but it's island life again and i've resided on one or another for a decade and more.
Italy would be 'ideal' as kids can go to boarding in Swiss, and we can ski in Swiss - and have a home base there - its also full of culture and great for sailing etc, modern amenities etc.
Malta i did look at... but it's a island, wife needs grand malls and all the essentials, and kids will need a proper education etc, but be within reach of their mother.
We'd likely spend 6 months in Europe...
4 months in Italy (summer) 2 months in Swiss (winter), we spent 4+ months in Europe annually prior to covid.
2wks-1 month in Africa (Kenya/Zanzibar).
Rest of the time likely Asia.
Making italy(europe) a home base doesn't necessary mean we want to live full time [**** that]
