I'd like to nominate Aaron Tveit (https://www.imdb.com/name/nm3117836/).
Age: 34 (can easily look younger, IMO)
Height: 6 feet
Rationale:
- Very solid actor, capable of pulling off drama, tragedy, and comedy.
- Plays a somewhat Finrod-ish character, the revolutionary leader Enjolras, in the 2012 film Les Miserables. He's quite convincing as a charismatic, self-sacrificing leader who cares deeply for his followers and maintains his courage of conviction in the face of inevitable defeat.
- In interviews comes across as polite, friendly, and generally very likeable, so I can also see him as the prince who is quick to sympathize and strike up friendships with Men and Dwarves.
- He can SING. He's starred in various musicals on Broadway and elsewhere. Here's a video of him singing "One Song Glory" from Rent:
