I ended up trying both solutions, not to sure on which one to go for yet:
Here is the solution with pages: https://jyllandguiden-no-f7f57c7a-84888adb63004.webflow.io/
Here is the solution with tabs: https://jyllandguiden-no-f7f57c7afac669130f5827.webflow.io/
The “pages” version works more as intended by having both “in” and “out” animation for each region-link. (And was the most straightforward to solve). But the animation feels a bit choppy, but still a viable option.
The “tabs” works well and is more fluid in its movement, I have yet to figure out how delay the link/content swap. If I figure this out then this is without a doubt my preferred solution.
But anyways, I am on the right path here - thanks again for the tips Eli11!
