The pastoral consideration is, as the deacon @fj2020 referred to correctly noted that it creates disunity and division in a sacrament that’s supposed to be about celebrating union. While the couple are both Catholic they’re marrying into each other’s families as well as marrying each other. Besides this, on a practical level it’s also messy to have a large number of non-communicants mixed with communicants as well as the fact that only a small number will be familiar with the gestures / responses.This isn’t a “mixed religion” situation, though – both the bride and groom are Catholic (although one is a convert). The “mix” exists because of the families of the couple, one side of which is (largely?) Catholic and the other side of which is (largely?) not. The pastoral consideration comes down to how to deal with the difficulty of explaining to family members who are not Catholic that the Eucharist is reserved only to those who believe it truly to be the Body, Blood, Soul and Divinity of Christ, and who are well disposed to receive it.
So, returning to the OP, 2 is pretty much a non-starter since in a nuptial mass the union of the couple is reflected in the the union with/through/in Christ through their sharing in the Eucharist. 4 is a possibility but the priest is likely to steer @Asinner and his fiancée towards having a wedding outside of a mass. You could however go to mass together the next day and, depending on the circumstances, even arrange a special mass - there’s a votive mass for any anniversary of marriage which could be used even for the 1 day anniversary. Ultimately though you need to discuss this with the priest who will be solemnising your marriage.
