I recommend getting a switch tester with a bunch of "silent" tactile switches.
They have a muted thock that is much less annoying to be around.
For me I settled on Gazzew Boba U4 Silent Tactile Switches (the 62g clear version) in my moonlander (also using colemak-dh). I've also been looking at the voyager since the thumb clusters look like they're in a much better spot than the moonlander's which can feel like you have to pull your thumb back further than it goes to reach the keys if you don't mod your board (I have no idea what they were thinking with that positioning, it's so unnecessarily far away from the base keyboard compared to their other keyboards).
But definitely get the switch tester, because everyone's preferences are so different and finicky.
If you want to shift your hands around on the voyager, you can only really shift up/down and not left/right because of how steep the middle finger is shifted up (aka how staggered the columns are).
Compare that to the moonlander where the columnar stagger is smaller so it's easier to shift left/right as well.
If you want a left/right shift and you're okay with two close thumb buttons, it might be worth going with the moonlander and add these key caps to "bring" the thumb cluster closer: https://www.thingiverse.com/thing:4948862
