keeb.io keyboards are the best for that kind of thing. I ended up going the ortho route and designed my own keyboard (I needed extra columns as all the ergo split orthos end at ; key)

But before that I bought all the non-ortho splits (Kinesis, Goldtouch, etc.)and keeb.io were by far the most versatile. I recommend Quefrency for compact layout (my fav is V3 where you could still customize the bottom row) and Sinc for regular size. I used Quefrency when traveling and Sinc in the office. Happy to answer any questions!
