I've been trying out voice attack and I absolutely love it.
My "jettison all cargo" command was "23 Skiddo", but I went ahead and disabled it since I'm just hauling legitimate cargo in my type 6. I'll probably re-enable it when I swap to another ship and start dealing with illegal goods.
"wheels up" and "wheels down" were simple to setup and have been a major quality of life improvement for the frequent landings that I make hauling cargo.
It took some trial and error the timings right for a "request docking privileges" script, but it was definitely worth it.
The final voice attack command that I'm presently using is "initiate long-jump." I use that when I'm about to begin a multi-jump journey in my type 6. The type 6 tends to overheat a lot on long trips, so "initiate long jump" synchronizes the hyperdrive and the deployment of a heatsink so that I enter hyperspace as close to 0 heat as I can possibly get.
Eventually I'll probably use voice attack to rapidly swap between my preferred power distribution settings.
