Unless you have a eu passports then it’s either 90 max in the EU per 180 days or look at the residency options.
Portugal you’ve already mentioned friends of mine were out there early last year just start the process, due to covid they have only just returned to the U.K. and that was solely to sell there house here and start looking for a lock’n’leave flat, they really enjoy life there.
If I recall correctly the Portuguese option requires only 2 weeks per year residency and the residency permit allows you to reside / work anywhere in the eu but has some property/investment requirements but I might be misremembering.
The other option I’m aware of in the eu is cypress that gives fast lane eu citizenship but ties up ~€3M as an investment for a number of years, oh to be in that predicament…
Farther afield Thailand are now offering some digital nomads a working visa but I suspect that wouldn’t work on a eu schedule.
Personally I’d be in Portugal some of the summer, ski season in Austria but wherever you end up enjoy.
