Shift or control is not too pen-friendly and therefore probably not the best way to proceed, but at least it doesn't break things for pen users in the manner that left vs right click would, so if someone wants to implement it that way, fine by me. Perhaps better: one could also look into making things automagical. One would then have a config option (in config file and perhaps in the menus) which, when enabled, would not force all aspect ratios to be preserved, but rather would make it easy to preserve aspect ratio if it looks like what the user is trying to do. What I mean is that the resize rectangle would visually "snap" to an aspect-ratio-preserving rectangle if one is dragging a corner rather than an edge *and* the aspect ratio is not too far from being preserved (by how much? perhaps within 15% + 10 pixels of 1:1 aspect, or some other amount of error margin to be determined by trial and error); and it varies freely otherwise. The user would get clear visual feedback about what is happening by watching the resized selection rectangle's corner fail to follow the cursor when things are snapping. This way, if I want to resize with preserved aspect ratio, I just need to aim close enough (with visual cues during the resizing to help me aim properly) and xournal will auto-correct it for me; if I don't want to preserve it, I can do it freely without triggering the auto-correction unless I'm trying to modify the aspect ratio just a little bit; but then I can try to do it either by resizing just one direction i.e. dragging on an edge instead of a corner of the selection box, which wouldn't trigger the aspect-preserving feature, or by doing it in two stages. (Also I could just disable the feature by unselecting the option if it gets on my nerves.) I think from an UI perspective this may be better, and wouldn't require the user to learn a shift-click combination (or guess that a different mouse button does something special).
