Make a regular print on real photo paper -- glossy or matte doesn't matter -- just to have a print. Than you can revisit the other options. The warm tone is beautiful, so color paper matching it or a warm tone b&w paper would be required to do it justice.
It's a very beautiful, moving portrait. literally bringing tears to my eyes for its gentle and respectful treatment of a full life. It speaks volumes, but speaks them softly with compassion and assurance.
Bravo!
