Spanish too. Francisco Javier -> Javi, or maybe Paco (Francisco), but Javi would be the obvious case.
Francisco -> Paco from Saint Francis holding a Pater Comunitatis title in Latin.
But, as a weirder case:
José María -> Chema
Luis María -> Luisma
Juan Manuel -> Juanma
José Manuel -> Chema/Josema
Juan Ramón -> Juanra
María José (women's name) -> Marijose

My personal favourite is Juan Carlos -> Juanca. Sounds great in British English.
My father's family is German and all of the males in the family only used their middle name for everything except legal and financial documents. For example, Carl Hans Schmidt (to pick a semi-made-up example) would introduce himself as Hans to everyone he met, and the family would refer to him as Hansi.
I always wondered if that was a German (or regional) tradition, or a fun family quirk.
(The males have all regrettably passed on but I asked my aunts once and they said they had no idea why or how that was a thing, that's just what they did.)
