Looking for Feat/long term suggestions for a Kensai Monk

Hi! I'm currently building a melee fighter for a nautical campaign that is kind of a mix of The Bride from kill Bill and Zoro from One Piece! I'm taking V. Human and don't really want to take Mobile since monks already move around well enough. I'm currently debating between getting a fighting style with Fighting Initiate and Slasher to give my sword attacks a little more utility. My current goal is to go monk all the way but have also been considering a dip into war cleric or fighter for action surge!

Edit: Fixed a sentence structure issue
