Mackerel, I would be very canny on what Uni you advise your DD to go for. On the whole, what you did can be a dangerous way to go, especially today with such an oversupply of graduates.
As a graduate she will need a brand. She either gets it from having gone to a fairly short list of highly trusted Unis, or she gets it from a specific course well regarded in the specific industry.
I'm sorry to say that 2:1s are not seen as equal across the board; there are some quite troubling statistics out there about levels of 2:1s awarded and grade inflation in some Unis. There is no way that degrees are standardised, I'm afraid. In fact, its the opposite- the sector is supposed to be as varied as possible, and offer all kinds of degrees from highly academic to very practical. There is thing called "parity of esteem" which means that we are not meant to express a view about which kind of education is intrinsically "better" - but standardised? definitely not.
Employers will buy a respected vocationally focussed course with a good reputation and good employer links. But a traditional non-vocational subject from the same Uni? that could offer the worst of both worlds, to be honest.
For your DD- making a quirky choice and hoping that employers will deduce from her A levels that she could have made a safer, more traditionally prestigious choice- there are two downsides to that. The main one is, she will get the teaching she gets where she actually goes; if she doesnt actually go to the safer RG Uni, she wont get the education they deliver, and her degree result wont be done according to their rules. Thats what employers are buying into- what happens post A level. The other is, employers are too busy.
