Ah, Rhapsody. I love their music, but I'm really not a fan of all the fantasy lyrics (One or two songs would be okay, but the whole discography, c'mon).
Anyway, I did a collab with NintenJoe 64 on the BadAss album that is symphonic power metal (but the quality is not that great).
Also, almost eveything from The Dual Dragons is close to this. Some work from Brandon Strader (especially his Skyrim remix), BONKERS or goat (his CV remixes are old now, but still great) too.
Check Dwelling of Duels too, they have great symphonic metal sometimes (virt and SnappleMan did a great Zelda arrangement a few months ago in that precise genre).
I hope it helps.
