I think you would be better of putting this question to a priest. It is one that revolves around canon law so a priest may need to take advice from a canon lawyer at the diocesan chancery. (Priests are not necessarily canon law experts.)
In general, a lot of bishops’ conferences publish lists of non-Catholic Christian churches and ecclesial communities that have valid baptism or do not. They all recognise baptisms from the Eastern Orthodox churches. Here in England & Wales baptisms in the Church of England and the Church in Wales, both Anglican/Episcopalian churches, are recognised. At the other end of the spectrum the Society of Friends (Quakers) and Salvation Army do not even have baptism so people coming into the Catholic Church from them would have to be baptised. There are also non-Catholic Christian ecclesial communities where baptism is considered invalid, e.g. Jehovah’s Witnesses. Then there are non-Catholic Christian ecclesial communities whose baptisms are considered doubtful and that usually includes the whole group of non-Catholic Christian ecclesial communities who call themselves Pentecostal.
As a Protestant, the Church’s law says if she is received into the Catholic Church, she will be a canonically be a Latin Catholic. However, she could always attend an Eastern Catholic church. If her legal canonical status matters to her she could apply to transfer from the Latin Catholic Church to an Eastern Catholic church of her choice.
If she were not baptised, she could choose to be a member of any Catholic Church. However, I would not like to say what will happen in her situation. As Pentecostal baptisms are treated as doubtful rather than outright invalid, she may receive a conditional baptism. With a conditional baptism if she was never baptised, she is baptised; if she was validly baptised nothing happens. I do not know the legal niceties of the effect of conditional baptism on membership of a canonical church. Therefore, I think this is one for a canon lawyer so this question should be put to a priest.
