You are more or less describing the Canary Islands.
You can live there talking English only, and there will be probably opportunities of work for your wife (that should however learn to speak at least functional Spanish).
Remote working for you, however, I don't think there is much occupation related to your field.
I lived on the Canarias for 3 years way back in the 90s. Loved it, but I guess it is totally different today. Nevertheless, especially Gran Canaria is on top of our list right now. It's still Europe, moving there is super easy. Weather is fine. International school should be there and a flight to Germany is a little more than 4 hours. So far sounds like an option.
I loved the Canary Islands ( I was only there for 2 days though ). Seems like it's big enough to have both big cities and small towns. And the food was amazing.
I know that being a tourist in Canary Islands is fun but is it a good country for a German to move to permanently? Does it have the kind of infrastructure and healthcare Germany has?
There is quite a bit German community there incl doctors, lawyers etc.
the big hospitals are also okay, although the local youth is fleeing the island.
