ADVICE NEEDED: choice of university for employability/student culture

I‘ve received offers from Goldsmiths UOL (for BA Fine art and History of Art + foundation) and Central Saint Martins UAL (for BA Culture curation criticism), currently waiting for UCL’s BFA Fine art
I enjoy creating practically but I also like writing about art, but considering career pathways (with Fine art, i can be an art teacher while with curation, I cannot), it seems as though CSM is not the best choice. However, CSM has a great alumni network (better than Goldsmiths) even though Goldsmiths has a great subject combination.
I find that these two elements are equal in importance to me so I have no idea what to pick. I think if UCL offers me a place then I will go for UCL (alumni network AND great subject), but for now I need to pick an insurance choice from Goldsmiths and CSM.
Any advice from fellow artists? Thanks
