I've not been playing any Neo Geo games so idk.
Here are the games on eshop I think are excellent (and also aren't hard super-precise platformers), idk which all you've played:
Axiom Verge
Stardew Valley
Wonderboy in Monster World
Thumper
Cave Story
Steamworld Dig 2
Enter the Gungeon
Crypt of the Necrodancer
Oxenfree
Axiom Verge, Cave Story, Wonderboy, and Steamworld Dig are Metroidvanias
Enter the Gungeon and Necrodancer are roguelikes so that might be too hard for you? But Necrodancer is a top 10 all-time for me.
Thumper is a p hard rhythm game
Stardew is a pleasant farming sim, Oxenfree a bratty teen simulator with great story and dialogue.
