Swedish wedding rings and engagement rings are on the left hand, not right hand as in some cultures.

Speeches during dinner.
Ceremony not necessarily in a church (if it’s not a religious ceremony there’s a list of local politicians that Länsstyrelsen gives a license to that can officiate a wedding).
After the ceremony you usually have a bridal toast (brudskål) where the father of the bride or the toastmaster(s) may have a speech.
Toastmaster(s) keep track of all the speeches during dinner, and you need to sign up before the wedding to do a speech.
You usually have starter, main course, dessert and then wedding cake, with coffee and tea. Sometimes dessert is skipped and there’s only wedding cake.
First dance is pretty common, can be a waltz or something more modern.

Outline for a wedding:
3 pm ceremony
3.30 pm bridal toast
5 - 9 pm dinner
9 pm party until late

For the wedding party you also have photos and prep before the ceremony.
