If you take control over your keymap and break out of the idea that the keycaps have to say what the key actually does, the problem is rarely insufficient keys on the keyboard to do what you want, even before you start mucking around with layers or other fancy things. A key that you want to have at hand, but only occasionally, is fine on a SHIFT-CTRL or CTRL-ALT or CTL-Win setup and very few things are default bound to such shortcuts in general.

If it's only a couple of such keys, it is generally not too difficult to use someone else's keyboard if you need to; slightly annoying but you will recover how to do whatever it is you're doing right now reasonably quickly.

I recently switched to this 64-key keyboard: https://mistelkeyboard.com/products/0a26d32ac1e3b1d2af2896e0... I've got a setup where I put one half on each armrest. After a brief adjustment, it's fine, I've got everything I need at hand, and I use the keyboard like crazy; I have not obsessed over setting up a no-mouse setup, but I can hit the mouse single digit numbers of times per hour pretty easily. There's plenty of keys.
