Very hard to establish decent credit without cc's. If she has a SSN or ITIN you can open a joint checking account with a personal line of credit attached to it to get her going.
More preferable would be for you add her on as joint to your oldest and best (low UTI, high CL, cleanest of any derog info) cc TLs.
If you add her on as an AU to any accounts you have that require her SSN or ITIN, she will also benefit from that for a while before FICO08 kicks in. She will also then start getting her own offers and can start building her own good credit independant of yours.
Cap1 has a card for people in her situation... little or no established credit history. APR is decent enough, the worst is an annual fee of up to $39. Really not bad at all, unsecured and she can grow with it bit.
