Hi D,
I walked the Norte (40 days from Irun to Santiago) in July and August in 2019. I don't understand any description of any of the many routes as "sightseeing with kinetic energy." In my understanding, the spirituality of every Camino emanates first and foremost from within yourself, and secondarily from whatever Camino you are led to walk. May you also find, as so many of us have, each special, precious soul you meet along the way to be your divine appointments to bless you on your journey. The reasons you gave for choosing the Norte are valid. Without question, you will get your gorgeous ocean scenery, the vertical challenges, and the smaller crowds." I did the walk for between $24-$30/day. I realize prices have risen, but I would encourage you not to make your decision on the potential difference of a few dollars per day one way or the other. I also encourage you to walk with a tent (REI has one called Milo that weighs 2 pounds). This will be a wonderful option anywhere along the Camino, but especially if you find yourself without lodging or want to camp next to the ocean and arise at dawn with a view (attached) that continues to inspire awe each time I view it. May God bless each step of your Camino knowing that it began the moment you knew in your heart, "I have to walk the
Camino De Santiago!"
