Intro FE game

What is a good fire emblem game to introduce someone to FE? I’m trying to introduce my boyfriend to it. He’s loved pokemon games and Zelda games, I’m thinking that the training/leveling up of units, and the weapons triangle might be enough to pique his interest.

For reference, I’ve played: blazing blade, sacred stones, path of radiance, radiant dawn, shadow dragon (wasn’t as much a fan), awakening, fates, three houses, engage. Of those I’m not sure what would be best; I’m leaning maybe awakening?

Not counting warriors and three hopes with this one.
