I am insulating not straight (walls are 5 degrees out) partition walls by cutting out 5cm wide rectangles, shoving mineral wool into the cavity then screwing the plaster chunk back over wooden backing. Then I use plaster filler to cover any holes, sand flat then paint. Problem is I can still see the rectangular outline in some places. Don't want to plaster skim or use wallpaper. What do I use to cover the rectangular outline? Needs to be thicker than paint but thinner than skim

For the price of plasterboard and tape&fill, weighing in the amount it’s bothering you, is it worth such a labour intensive approach versus just taking all the plasterboard off one side, insulating then putting back new sheets?
No that's far too much labour and there are electrical cables hidden in the partition walls a lot of which are not midway in the cavity (pressed against the inside of the plasterboard) chances of getting the plasterboard off without damaging cables are low.

What about using Polyfilla Smooth over (https://www.amazon.co.uk/Polycell-S...phy=69219&hvtargid=pla-4584001457396972&psc=1) just on the rectangular cut out plasterboard? Then it will be smooth
I did use an orbital Sander and used quick fil the result is in the above photo
