To be honest, I like the transition on Ajan Kloss as it is. Not everything needs an establishing shot, and I don’t think adding more of them really addresses the film’s pacing problems.
I mainly think it helps because we never get a look at what their base actually looks like in the movie. There’s no sense of location in Ajan Kloss, it always just feels like they’re on a set somewhere that’s sometimes dark blue and sometimes bright yellow. This one shot gives you a better idea for the rest of the movie of where exactly they are in the inner-base scenes. It may be the most obviously cgi shot in the movie if we use it, but ironically it may help the Resistance base feel more like a real place and less like the awkward fake location that all of the recycled TFA Leia scenes have to be contained.
Also, I really do think establishing shots can go a decent way in at least making pacing more bearable. I’m reminded of seeing Batman v Superman in theaters and getting whiplash every time they cut to a new interior location, vs watching the extended cut on home video and thinking “oh, there’s all the transitional shots; guess they cut them all to make more time for nonsense dream sequences in the theatrical.” And Rise of Skywalker definitely gave me some BvS vibes in the theater (though probably for several reasons).
