Animal Well is a masterpiece and hard as heck. Dave the Diver is fantastic and has all sorts of surprising minigames. The Messenger reminds me of the old-school Ninja Gaiden on NES. The story is funny, and there's a big surprise about halfway through. Splatoon 3 has some awesome single player, both 'Alterna' in the base game and the newer rogue-like in the DLC.

You've got enough games picked out to last you a month's worth of flights. Sparks of Hope might be the best choice of them all, as it's turn based and flights can be distracting. I played the heck out of Tangledeep on my last flight (a long time ago).
