From my RC sailplane experience, I would (generally) avoid these.
I would (for a straight run) much prefer a .060" CF rod in an etched Teflon tube housing.
The ones that you showed usually have "hysteresis" problems, a fancy way of saying slop between the inner and outer parts.
The first thing that happens with that on a curved run is that the inner moves laterally in the housing at the bend, before any movement occurs at the end of the rod where you want it.
On a servo driven application, you can alleviate that a bit by spring loading the surface with a light simple music wire spring. That takes the free play out of the system.
I have also use the Sullivan housings with the .032 or .062 stranded cable. These work OK, but are heavy, and since in an RC glider application are normally going to the tail, that is bad (extra weight behind the CG on a long moment arm).
That is where the etched Teflon tube, fully secured, and the solid carbon Fiber rods come into play.
Additionally, the larger sizes of etched Teflon tube are basically "one size fits all" since you can warm them, and stretch them out, reducing the ID to be just a few thousandth's over the CF rod, all but eliminating "hysteresis" in that system.
Yes, I really am a glider geek.
Some of it does have applications for U/C though. All of the "new" CF tubular push rods with ends are pretty commonplace in the glider community, for instance. MPJet sells a boat-load of different sized threaded ends, and ball linkages, for example. So many sizes and options there.
If I were to use this type of system, it would be supported full length alongside a profile fuse, where it would be easily replaced if you didn't like the results.
I like the out of the box thinking, though!
