"what operations would you view this as the go-to took rather than a traditional plane or powered router?"
I don't like noisy routers and didn't used to have a wide selection of woodies to hand, so it was my
go to for quite a long time, particularly grooving as I think my first woodie was a rebater.
Frame work; picture frames, doors, windows etc. 16c coffers and chests, anything really that would require grooves, rebates, beading, lipping its very versatile.

You don't need a panel raising plane as Roy has, two grooves and a block plane was how we did it on our C&G 585 pt1 all those years ago, (wistfully looks skyward). making our (raised and fielded) two panelled lower and upper glazed doors.
If you dont have any wood to suit those frame items to hand, then you could make a box or two, sir Roy does a good box;

la Roy as yet)
You may need to make up a sticking board or such if you don't have a holdfast available, and possibly a peg in the front of your bench to aid the face vice in holding long lengths when grooving n rebating for framing.
I think i read through the blog from thingy-ma-jig at Cornish workshop after butchering a few lengths, in retrospect its worth reading beforehand ;http://www.cornishworkshop.co.uk/combinationplanes.html
Have fun with all those shavings.
