Exactly what @Julien stated.
Totally get the limited time in the shop issue as well.
Do whatever is fastest when you need something done.
Last thing you want is to struggle and get a bad taste for F360 when time is of the essence.
Otherwise chip away at the basics as time allows with F360.
Follow along an exercise to a T and machine it as well with some scrap material.
Getting down the workflow and understanding how it works start to finish will make you faster - to the point F360 is no longer seen as a hurdle.
