LinuxCNC (at least Axis) can be controlled by keyboard - F1 is especially handy to stop the job in progress if anything goes wrong. Arrow keys can be used for jogging, with shift it uses max travel speeds but dedicated CNC pendant for jogging is on my TODO list as well as standalone DRO with 7 segment displays.

So far I've tried a few pendants, starting with a games controller, some kind of media production controller, and some off-shore low budget purpose made dedicated CNC pendant. The games controller was by far the most useable but it's made out of the wrong materials, made for childrens' hands, and doesn't have all the right mechanical inputs (I need a wheel). The media thing was unsatisfying but tantalising in some ways.
I've been psyching myself up for a doing some sort of mostly faithful copy of legit OEM controllers I use from time to time, like Fanuc for example. Some years ago I used an old Maho that had a really nice wired pendant. It was really solid, had some heft to it, and my recollection is that failing one or two functions had every one might want in such a device.
Also, I think you're right about wanting a standalone DRO with 7 segment LED displays. For a lot of jobs I find that a DRO hits the sweet spot with being easy to use, easy to read, and having the functions I need. My only real complaint is that I think I want one with a larger read out, so I can push it well out of the way and still see it properly.
