Op, as others have said, can she go to a uni fairly close to home, but living away, so she can still see you all regularly.
My DS is finishing 1st year doing Chemistry at a good uni, under an hours drive, similar on train to nearest main station. We have seen him loads, been over there for day trips, or he has come home, sometimes just overnight, my DH also went a couple of evenings (tied in with bringing stuff back at holidays). In fact in spring term we saw him almost weekly for various reasons, but not at all since Easter as he revising and now working weekends. We also whatsapp and facetime loads.
He worked in 6th form, we weren't that bothered if he worked at uni, and actively discouraged it initially whilst he settled in. He has recently started back with his former employer, but in uni city. So he will go back and forth in summer hols, to do weekend work and any weekday shifts he can pick up. But a lot of his school friends go back to their old 6th form jobs in holidays, would that be a possibility for your DD?
He has had a ball. Never been a lads lad, but made loads of friends, male and female, out partying a lot, but also has a strong work ethic. Still waiting to find out exactly when we will see him after exams finish next week - depends on end of year social life I think!!!!!
He is hoping to do 3rd year in placement, and will consider overseas as well as UK.
I think if your DD intends to stay at home even for placement year, that is very sad. I know everyone is different and I took a while to settle at my uni, but am so glad I left home and got that independence and am so glad DS is doing it. He has definitely grown as a person since Sept.
