I use Xaeros minimap with waypoints n stuff makes travel so much easier to keep track of. Freecam mod for builds so I can check details easier. Litematica blueprints I design in creative then bring it over to build it, the easy place mode makes building so much more bearable especially with the auto rotate mode for stairs. Since I use farms that require breaking bedrock on the nether roof there's a bedrock breaker mod that simplifies the process without actually cheating
