Well if Edward lives then Northumberland continues to rule the council until Edward's majority - though that's only going to be a couple of years tops - Edward was already taking a keen interest in state affairs and religious ones - Northumberland was also keen to involve the King more.
In religious terms you have a much more Protestant England - Edward was as zealous a Protestant as Mary was a Catholic - Edward's England won't be the Anglican Elizabethan Settlement or the pseudo Henrician Catholicism of his father's later reign.
Edward will have a more international view of religion which is likely to lead him to offer support to "fellow reformers" - Elizabeth had a much more cautious approach to this and her early support for French reformers ended in disaster and in her later reign she was very unwilling to offer support to Protestants who were in her view in open rebellion against their monarch.
Edward with a more secure view of his own legitimacy might have a differing view and be more willing to offer support to Protestants in Scotland, France and The low countries - which will bring England into conflict with Spain and France.
In terms of his marriage - he was to a certain extent very opionated on his own status as a King - he isn't going to look domestically unless all other avenues fail - Henri II was keen on the match and Elisabeth's dower was large - Edward will wish to pursue that match irrespective of Elisabeth's Catholicism - it will of course be interesting to see how the Catholic Elisabeth is received at court and by Edward (who was quite frankly as intolerant as Mary on the issue of religion) if it goes ahead.
If the marriage fails to happen or Henri II looks elswhere then the options narrow - If Mary Stuart is widowed as in otl then she becomes a target again (and her own vanity might allow a marriage with Edward VI - her religious convictions were a moveable feast - on her first widowhood she was determined for a match of equal status to her French one - it was only that she fell for Darnley that she married him) - Edward might find favour for a match with Mary with the Scots - who will be keen to see their Queen out of the way again and marriage to a Protestant even an English one would be supported
As to Mary - she stays at home unmarried and unwanted - her age is against her in terms of diplomatic value and Edward by 52/3 was already out of patience with her determination not to see the "religious light" - she may become a slight focus of rebellion if Edward's religious policies continue in the direction they were going in before his death.
There is zero advantage to Edward of marrying her off - suspect she will consider to live quietly and get herself into trouble for continuing to hear mass etc.
Elizabeth has more advantages in terms of age and looks but she is nominally illegitimate - if she's still unwed when Mary dies then her attraction goes up a bit....she does have money (Henry provided quite well for his daughters) - especially if Edward is still unmarried or childless.
Edward is unlikely to force her to the altar unless there is a huge advantage to the country or him personally.
The Grey/Dudley marriages came into being before the King's illness grew severe - they may go ahead - though the Suffolks were initially reluctant (they thought marriage with a younger son for Jane wasn't the best match) - Northumberland was in favour so the King might support the match - Catherine Grey stays betrothed to Pembroke's heir.
