One thing to consider do you speak any of these languages (i.e. French, Italian or Spanish) or at least willing to learn?
Just an opinion and my experience of course but I think learning the language greatly helps from meeting new people and to integrating into that country. Of course you could live in a tourist town which have a lot of English speaking inhabitants but then house prices are probably going to be higher and you're probably not getting as an authentic experience
We're not quite as bad as we used to be, but step outside well travelled zones and you'll have trouble finding French people which are actually fluent in English.
If you don't want to learn the national language and want to live somewhere good and quiet, out of the three countries I think France is probably going to be the most challenging one.

I worked through think stats a couple of years ago. But I was lost on where to go next. It seems like there’s a gap between textbook and working world stats.
I wanted things like design of experiments and hierarchical bayes methods, logistic regressions, and other somewhat advanced topics, and most of the things I found were poorly written R documentation. Which from a development perspective is too much effort to grok, read papers, and then port the code to python.
It really sucks that R is the go to for so much when deploying R in a production environment is a pain or not possible.
https://kubernetes.io/docs/tutorials/ is a good place to start, you can use minikube installed locally or else you the interactive sessions provided by katacoda which gives you a quick way to get familiar with it
