Great idea----Kreg is the big dog in that field, or at least in my experience here in the USA. They're great for hidden fastening of interior panels without exposed screw heads etc.
For light use such as we typically do on these sorts of build outs these work perfectly: https://www.kregtool.com/store/c13/k...reg-jigreg-r3/
This same kit is on eBay and Amazon for less I'm sure.
Like most cool tools once you have one you'll find more uses for it, if my experience is typical.
