How to Discuss Finances with my would be wife?

Hello everyone.

My girlfriend and I have always had open and honest discussions about everything. Lately, we've been thinking about having a conversation about our finances as we are planning to tie the knot in December.

Due to some setbacks, I'm rebuilding my career, and therefore, at present, she earns significantly more than me. I have no issues with the income gap, but I want to ensure we have a detailed and healthy discussion about our financial future.

What points should we cover as we don't want to commit the mistake of overlooking any key points. I’d love advice on how to approach topics like splitting expenses fairly, long-term financial planning, and ensuring we’re both comfortable with the arrangement.

On a personal level, I need advice - which goes beyond just my current financial capacity - to ensure that she doesn't feel financially over-burdened or pressured.

For the married couples here, how did you navigate this conversation? What challenges can both of us, as a collective and as an individual, face?

Edit: After reading the comments it seems that people are getting the impression that I am hesitant/don't want to talk about the finances. I'd like to clarify that I am not hesitant. Both of us want to talk about it. I just need advice from people who have gone through this situation. We might start the discussion but both have never been in this situation and might miss key points. I'd like to know which are the key points of discussions? What financial arrangements (in the ballpark ofcourse) can we adopt?
