I don’t know if this helps but I restringed my acoustic that was sitting unused backwards around May/June and tried to learn righty (I’m lefty).
It does still feel awkward but after two weeks of practice every other day or so I could play open chords, with some transition delay. Arpeggieting the chords was full of errors as I didn’t have a good sense for where the picking arm was in relation to the strings. All I did at that point was chords and the 1 2 3 4 , 1 3 2 4 synchronization stuff. (It was interesting that although I play with a karate chop kind of grip lefty (fingers extended), it felt more natural to have all fingers contracted righty - I did not try to change it).
After that I played maybe once every two weeks or so. Now I can play barre chords too but not instantaneously. I will sometimes play over backing tracks but it’s pretty frustrating because I know what I want to do yet I can’t do it. I can’t do vibrato or anything yet so it sounds bad haha. In terms of fretboard visualization it wasn’t too bad to flip the map, except initially in cases of e.g. A minor pentatonic position 3 5, 3 5, 2 5, 2 5, 3 5, 3 5, ascending, I would get confused and do 3 6 instead of 2 5.
By the way regarding the strategy of going fast while accepting errors to get the motions right, and then going back to fix stuff doesn’t make sense while playing with two hands simultaneously so far, as I don’t have basic synchronization down. So perhaps practicing the picking hand by itself to start out with good habits might be the way to go, but I haven’t tried it, I just went for whatever felt ok slowly. It kind of seems like a double escape but we’ll see how it goes.
I got carried away here but I don’t think you have to be ambidextrous (I am not) to learn the other way - there might be a penalty in some mechanics because of interference but I think most things will progress faster because you know what to do and what to expect.
