BA in French and German. Pretty useless on its own, frankly, without postgrad qualifications to back it up (which I managed to get over the next few years with help from a) then employer and b) it was a PGCE, so partly funded). What was much more useful was learning to type, learning how to use various computer packages, and the customer service/admin evening work I did part-time while at university. And then learning to drive when I was a bit older.
It really depends on what the young person wants to go into, but don't think degrees are the only qualification out there. Having a degree does open doors, and I'm very glad I stuck mine out (I hated the ethos of the uni, it was very stuck up), but in my experience, the BA, or BSc, or whatever, is a foundation level qualification for many jobs.
Unless it's something super vocational, like nursing, or some types of engineering, or medicine you will have to keep acquiring qualifications and attending training for the rest of your working life. (Even applies to nurses, doctors, and engineers, thankfully....!)
Oh, and for what it's worth, if I could go back, I'd choose something that I genuinely liked, such as English, or Communication Studies, or something OR something VERY vocational like, I don't know, Financial Management.
Given that it took until my mid 30s before I was offered ANY jobs that had anything to do with my BA. And I really would have preferred to take the approach they do (or did) in Germany, where you take your degree over a longer period of time, and often work alongside it. Part-time, online, distance courses didn't really exist when I was 18 though, with the exception of the OU which was drastically expensive even then.
One way to approach it might be for them to work out what's most important to them - lots of money, or a subject they enjoy? It's also apparent that we are in the early days of COVID-19 transforming pretty much our entire way of life, which makes it trickier than usual. All of the things that used to be taken as a given as part of the uni experience, like making friends at Freshers' Week etc appear to be "under review". (Glasgow is an example of this right now.)
If they're old enough, would it be worth them trying out some of the free open learning courses on platforms like Coursera and the like to see if there are particular subjects they really enjoy and would enjoy studying a bit more? You might also want to have a look at the Student Room website, which has some great resources on there.
Best of luck, whatever they decide.
