The keyboard rabbit-hole gets pretty deep. I started off wanting a nicer typing experience, and ended up realising so much about the traditional keyboard designs didn't make sense to me (here's someone nicely summing up the reasons why https://www.youtube.com/watch?v=rrska7UU7BE).
For me the optimum is a split 34-key keyboard (the open-source Ferris Sweep https://github.com/davidphilipbarr/Sweep) with a custom keymap firmware (QMK).
Going even deeper, you can generate a PCB layout that's personalised to the shape of your hands: https://github.com/ergogen/ergogen
