Having trouble getting this effect to play out well using crescendos. Seems like MuseScore only likes to do crescendos not by note so I'd have to split the note up which causes a rearticulation that sounds terrible.

Like the first synth chord swelling? You can try swapping e.g. a whole note for 16 16th notes tied together, that shouldn't re-articulate but should change dynamic at each point
Or manually edit the velocity of each note
But to get a proper smooth swell I think you need a vst. Musesounds strings can do it iirc, but there's no synth musesound
