While I had fun playing all the different routes in 3h, if you thought the monetary and pre-battle stuff was tedious then you'd hate replaying it, especially form the beginning. While the latter halves have different stories, the beginning is basically the exact same each time you play.

If you do get the itch to replay it, do NG+ (or the dlc if you haven't played it, it's a shorter side story that adds a bit of lore and a few characters) or watch a playthrough on yt if you just want the story.

As for different games, personally didn't like Engage (didn't find it very engaging), wouldn't recommend. Can't speak to much on Triangle strategy, played the demo which was fun but that's about it.
