Like others have suggested start with what you can see.
-engine/airbag lights.
-seatbelts
-mirror/window switches working,
-heater/demister working
-all lights
-tyres
-wipers and wsw pump
Then underbody will likely need
castor bushes, sway bar links, rack boots, strut boots, strut mounts, engine and trans mounts
engine will be rocker gaskets, sump, extension housing seal. Remember oil leaks have to be dripping, if you clean it well enough you might be able to put these off
Just remember the shop will want to find something to work on regardless so I'd just leave them a couple things to do like engine and trans mount, keeps them focussed on major items
