Regarding the things you don't like, my solution was to get the foot pedals. I have the three pedal one and use one pedal as FnShift and another for shift. I've then also mapped some common things like ESC to the Fn layer, so I can press it with ease by hitting the FnShift with my foot.

Also, for when I don't feel like using the foot pedal, I've moved some keys slightly: CapsLock to Tab, Tab to left shift and Left Shift to FnShift.

When I started using the keyboard, I also mapped lots of common things that I found awkward to the Fn layer, especially the left side that's completely unused. But as I got used to the keyboard, I've sound I don't really use them anymore and don't actually remember what I mapped to the layer, only really using my ESC mapping and the default numpad mapping.

I also have the three pedals! I couldn't get used to use them regularly as much as I wanted and I some point I simply stopped.

My mapping was/is ESC, Ctrl and Shift. Never thought of using a FnSwitch, that's actually a great idea

It took a little bit of getting used to, but once I did, its been great. I don't always use it, sometimes I'm just not sitting straight at my desk and its seems like effort, but when I'm typing heavily or coding, I typically do. It makes typing very pleasant.

I didn't use it to toggle Fn, but to shift it (just in case it wasn't obvious), since keeping my foot on it is really easy and letting go is the quickest way to switch back.
