What's the minimum height for the spawning area of a mob farm?
Considering a standard mob farm design, what's the minimum height I should build the spawning floor so that I'm sure I get 100% efficiency (no other mobs are counted toward the mob count cap)?
I don't feel like lighting up every cave yet, and I desperately need a working mob farm.

If your concern is solely limited to other hostile mobs lowering your grinder's efficiency, then quoted from minecraft wiki,
Hostile mobs (and some others) that move farther than 128 blocks from the nearest player will soon despawn (see Despawning), so even with a larger chunk loading radius, the mob spawning area is more-or-less limited to spheres with a radius of 128 blocks, centered at each player.
What this means is that to get 100% efficiency, you should build 128 blocks above the tallest terrain you are at. ie 128 blocks about ground level.

How high does my mob farm need to be?
How High Does a Mob Farm Need to Be? Mob farms should be a total of 22 blocks in height to kill the mobs.How deep does a mob farm have to be?
How to set up: Dig a 1\xd71 hole down 23 blocks (minimum). With fall damage mobs (or players) don't take damage for the first 3 blocks and take 1 damage (half a heart) for every block over 3. So to do 20 damage (10 hearts) the needed distance is 23.Minecraft wait what meme part 269 (Crazy Multi Sword)
