I'd say JRPG support has been the best ever for Microsoft consoles thus far.

FFXV
Final Fantasy 15 Pocket Edition HD
World of Final Fantasy Maxima
Final Fantasy Type-0 HD
Xbox One X patches for FFXIII, FFXIII-2 and Lightning Returns FFXIII
FFVII, IX, X HD, X-2 HD, XII
Kingdom Hearts 3
Tales of Vesperia Definitive
Valkyria Chronicles 4
Valkyria Revolution
Monster Hunter World
Ys Origin
Pier Solar and the Great Architects
Shining Resonance Refrain

a few ones that aren't typical JRPGs like Dark Souls 2 and 3, Nier Automata and Dragon's Dogma Dark Arisen.
and a couple of smaller ones.

Far more and better titles than what the original Xbox and Xbox 360 got.
