Review bush condition, if there are shot bushes there is no point getting alignment done until those are replaced.
I am sure are is improved alignment settings out there, but the issue will be finding a garage willing to adjust to them- you would most likely be looking for a specialist in wheel alignment.
For their indemnity, the big nationwide garage chains just set to what their computer says - and that is it! - as an example of how strict they are (not applicable to our Golfs), if your car is something weird that isn't in their computer database for the machine, they wont touch it.
From the readings you have added, assuming the powerflex anti lift kit is still good, it looks like either Left top mount has sagged or front control arm bush is on the way out - if it is loose you may be finding vague steering and tramlining.
Rear left look suspect for failed bushes - for OEM bushes the quickest option is replace entire arms.
