Cherry MX Brown switches are normally recommended for very light activation pressure and "super-fluid motion". That is an option available.
You can order parts for yourself, make it yourself, and everything. It is opensource hardware, built around the "teensy" opensource controller. But it ends up cheaper just to buy the keyboard unless you want to build something custom.
While it sports up to 32 custom layers, it does lack a dedicated hardware module for a mouse. It is completely programmable.
I only mention it because I love mine.
