That list of stuff is what I have would expect on a "regas" (which is used almost interchangably with the term "service" as it is easier to sell to customers).
At a reputable establishment, which is where I suggested the OP visit, much and if not all of the stuff on your list should be being done routinely. It is mostly visual checks and I would be alarmed if a garage were not doing it frankly. Stuff like checking the condition of things like pipes, the connectors, the operation and so on, prior hooking up the machine is just what a half decent vendor should be doing with every car. Much of the other stuff on your list is done automatically by the machine that they hook your car up to. Like purging and recovering existing gas and lubricant, leak testing, etc. The machine isn't sitting there doing nothing for the 40 minutes it is hooked up.
And pretty much every garage will take a before and after temperature reading at the vent, which naturally enables interior operation checks too.
Essentially a regas is a system service.
