If you using resolve, there is a blanking fill open FX filter that does this automatically, for social media usage.
Blanking Fill
This plugin is specifically designed to quickly fill black frame blanking with a stylized image derived from the clip itself, to make blanking less intrusive for viewers in documentaries and news segments. In the following example, the Blanking Fill plugin is used to add image to the left and right of “pillarboxed” standard definition 4:3 video that appears within a High Definition or Ultra High Definition 16:9 aspect ratio.

You could also do this by duplicating the original track on the timeline, blurring it, and the duplicate on top you simply crop.

If you want to do it in fusion, you could do something like this. (I've used blue circle as pattern for this so you can use it to, but obviously you would put in your own footage instead)

Just copy and paste this code here into your clipboard and than in fusion node area. And you should see the same thing.

Usually when you go from 16:9 horizontal to 9:16 vertical you lose some resolution if you want it to fit in so you will have to do some resizing and fitting.
Resize node and letterbox would do the trick. Resize for resizing original you want blur or you can use transform tool and background node, but resize is somewhat easier, and you would use letterbox for fitting one aspect ratio to another. Set Domain simply limits the rendering area and acts as crop here.
I would suggest you use Blanking Fill open fx filter in resolve since its probably going to render it quicker and its more convenient to use. For the record I hate that type of effect from eye soar point of view, but if you wanted to do it or needed to that those are some ways to do it.
Its hard to account for specific masks or whatever you are using since I haven't seen it and don't know how they are constructed, but depending on what you need, similar approach can be used.
The other methods might involve using fusion clips or various other methods which conform all elements to timeline resolution automatically so you only have to change timeline format from horizontal to vertical, but because there are lot of resizing and suspect ratio change , depending on the complexity of what you do in fusion, you would need to set it up as you work to accommodate for resolution and more importantly aspect ratio change.
Most tools have auto resolution option in the image tab which will conform them to same resolution, usually of the timeline but it could be of the clips, depending how you work. If you using fusion clips than all elements follow same resolution which means if auto resolution option is turned on, they all change correspondingly.
But tricky is the part when you need to change aspect ratio, like going from horizontal to vertical. Because you don't want your logo or text to be squeezed to fit the new vertical aspect ratio with same resolution, you want it to change resolution but not aspect ratio and for that you usually want to use letterbox tool , which allows for that.
