Do I have to update IRCC about this and it so how? What would I need to provide from her end as per documentation? Or would I just have to mention her details?
It's best to update IRCC about the change. I raised a web form to update my case once I had the marriage certificate apostiled, about a week after the wedding. IRCC responded with a very long boilerplate email — most of it won't be relevant to your case — but here's the relevant bit:
If the newly eligible family member is a spouse, common-law partner or dependent child who is already a permanent resident or Canadian citizen, only a copy of the birth certificate, marriage certificate or proof of common-law relationship and a letter of explanation are required.
I submitted the requested documents and received an acknowledgment of receipt from IRCC a few weeks later. IRCC had no further questions, and the PPR arrived a couple of months later.
I had a similar situation in late 2022 while waiting for the outcome of my EE PNP application (post-AOR).
If she's already a citizen, it shouldn't affect your application.

Thank you for the reply. Currently I’ve got the PNP nomination and I’m waiting for the next draw.
She is already a citizen.
Should I marry her and add her onto my file before accepting the ITA or should I accept the ITA and file my PR application and then raise a web form? Which would be the best and cause minimal delays to my application?
What we are planning is: file for my PR, and then get married, and send marriage certificate through web form. Or can we get married after the ITA, then I add her onto my profile and upload the marriage certificate? Sorry I’m not too sure what the best option would be.
