The Way from Lourdes is greatly improved from what it used to be, and 2 at least of the best Refugios on the Way are found there, especially the truly magnificent one at Lourdes itself ; and at Arudy, for as long as the cat and his priestly friend shall remain there as Angels of the Way.
The only strong advice I'd give is go via SJPP rather than the Somport -- the Aragon Way is very beautiful, and some parts of the Way there from Arudy or Oloron are memorably sublime ; nevertheless the physical & mental challenge there is not insignificant, and the route is also longer, harder, and takes more time.
It is different for those following the Arles Way that leads there, or those starting at Oloron, because there is a psychological and spiritual continuity for them -- that I've found to be better preserved for a Lourdes & Santiago foot pilgrim by continuing after Lourdes through Oloron to SJPP etc.
