If you don't already know about it, I recommend https://www.keybr.com/ for learning new keyboard layouts. It introduces letters one at a time and waits until you hit a threshold speed before introducing the next one. If you commit to doing 15-30 minutes a day consistently, you can get to an acceptable speed more quickly than if you try to learn in an ad hoc way.
I'm in the same boat as OP. I've used keybr and https://monkeytype.com/, and while doing the exercises, I get pretty close to the speed and accuracy I had using a standard keyboard and qwerty, but I get much worse on both fronts when typing in the real world.
