Hi Oscar,
welcome to Asturias!
We are on the other side in the east of Asturias, near Cangas de Onís and have been living in the area for a year now and observing our property and slowly getting to know other people and projects around. We are really happy and still in love with it. The beauty never ceases to surprise and impress us.
The microclimates and hardiness zones within the strip from the coast to Leon vary greatly and also depend on your altitude. We are also about 20km away from the coast on 234m above sea level and might have similiar conditions to yours. But it all really depends on your specific context and conditions, like previous use, soil compositions,....
What worked for us is that we changed our jobs and clients to be able to work from remote during Covid, so we could move to an appartment nearby, so we could camp on our land and study it in detail for almost a whole year.
At the moment I am working on a holistic, self-reliant and regenerative design and business ideas for the land as well and would be willing to share my insights with you, as well as get to know your project a little better. Occasionally I need to go to Oviedo or Gijon for administrative stuff, so could pay you a visit if you happen to be there.
We are just also getting into the whole building permissions and regulations topic for our buildings and trying to figure out how to go about it. It also depends highly on your local administration.
Another thing you could try is to check out the nearest wwoof hosts in your area:
https://wwoof.es/hosts/search and connect with those guys.
So far we only found a small range of organic seeds at organic food stores. But often your local nursery might have them or can order them for you.
Here is an online nursery in Galicia:

You could also try to these well known shops from France, Austria and Germany and have them delivered to Spain:
https://essembio.es/
https://www.graines-baumaux.fr/
https://shop.arche-noah.at/
https://www.reinsaat.at/shop/EN/
https://shop.sativa-organicseeds.com/
https://bingenheimersaatgut.de/
https://www.dreschflegel-shop.de/
Don't have any experience with spanish organic seed suppliers yet.
Best, Andreas
