In your Blender file, head to Scene Properties > Units and set Unit Scale to 0.01
You will find that your view distance has been drastically reduced, so open the viewport side panel (N by default), head to View and correct the Clip Start and End values as they will have been scaled down (I usually set them back to 0.01 and 1000 respectively but whatever works for you).
Any existing objects in the scene will now need to be scaled up 100x to return them to original size, but new objects should be created at the correct size. If you have any constraints with specified distances (i.e. Limit Distance) you will find that they have been scaled down 100x, so you will need to scale them back up.
The same goes for any animations with Location keyframes. I find the best way to correct these is to go into the Graph Editor and set the pivot point to 3D Cursor, ensuring the cursor’s Y position is 0.
Then hide all curves except for Location, select all keyframes and scale by 100x in the Y direction. You should now find that your animations no longer resemble sleep paralysis demons (if they still do, check through the list to see if any of the channels are locked or hidden when they shouldn’t be - I’ve been bitten by this a few times in the past).
As for axis, I usually use Negative Y as my ‘forwards’ direction. I believe this is the default view direction for Front Orthographic (NumPad1).

Hope this helps.
