Well, Chrono Trigger's fairly short unless you're going for alternate endings via NG+ (and even then each subsequent one's fairly short since you can carry over levels, techs, equipment, etc and generally the alternate endings are based on how far you got in the game when you opt to fight the final boss, and what all has happened and been resolved/not resolved yet). I doubt you'd get real burned out on an initial playthrough.
Anyhow, general advice from some copypasta I wrote for times like this: If you want some decent starting places, consider Final Fantasy VI (IV, V, and VII are also rather well liked), Dragon Quest (III, IV, and V tend to be fan favorites), Paper Mario (both the N64 and Gamecube ones; also Super Mario RPG for the SNES, though it’s not quite the same), Mario and Luigi (especially Superstar Saga on the GBA), and Chrono Trigger for Turn-based/ATB systems, and Tales of Eternia/Symphonia/Vesperia (playing through most of the localized games in the series, those have struck me as good starting points) and some of the Mana games if you want real time combat. Also plenty of other series (Baten Kaitos, Breath of Fire, Grandia, Legend of Heroes, Lost Kingdoms, Lufia, Lunar, Mother, Phantasy Star, SaGa, Shadow Hearts, Shin Megami Tensei, Star Ocean, Suikoden, Valkyrie Profile, Wild Arms, etc), as well as standalone games (Infinite Space, Lagrange Point, Radiant Historia, Rogue Galaxy, Skies of Arcadia, Vagrant Story, Xenoblade, Xenogears, etc) if you find yourself liking them.
Big thing to keep in mind is that there's a lot to pick from (even more if you're willing to look beyond the mainstream for more niche franchises like Atelier and Ar Tonelico, or go for fan translated ones as well, as they're popular to patch into English, even if it takes a long time to translate), and even if one particular series or gameplay style doesn't do it for you, try another one rather than writing them all off.
That’s also not taking into account the swath of tactical JRPGs as well: Dept. Heaven, Disgaea (as well as various other NIS tactical games like Makai Kingdom, Phantom Brave, and Soul Nomad), Final Fantasy Tactics, Fire Emblem, Front Mission, Langrisser & Growlanser, Ogre Battle & Tactics Ogre, Shining Force, Super Robot Wars to name some.
End pasta.
JRPG doesn't exactly mean "Final Fantasy-esque" in gameplay/theme, though I suppose that's the stereotype. If you ask me, it's more of a "region of origin" designation, and you can apply further descriptor to them since they can cover a range of different gameplay and/or thematic styles (same with WRPGs).
