I like alignment as a cosmic force, inspired by Moorcock's eternal champion etc. I do find it useful as a rough shorthand for NPCs, but that could be served by a sentence about their personality as well, or how some other games do it: an adjective and a noun. "Inquisitive Scamp," "Amenable Host," etc.
A5E did a good job with it, I feel. Most creatures don't have alignments, except for what we'd called "Outsiders" in 3e. Fiends, celestials, etc. Powerful clerics etc. can get alignments as well.
Of course, I also like alignment having a function... certain spells, effects, etc. relying on/affecting creatures that have them, or sentient magic items having conflict etc. with them.
