Blaze Farms

Blaze farms are slightly modified on Vanilla+ due to spawner AI being disabled.

Semi-Automatic Blaze Farm

You do not need to place the fence gates in this design due to spawner AI being disabled.

You can use a beacon in the Nether by allowing it to have direct access to the bedrock roof since beacon beams pass through bedrock. This lets you avoid dying to hunger while using the farm.
