Panasonic FM SeriesUltra Low ESR same as FR series, Low Impedance(40 % to 70 % less than FC Series)Endurance : 105 °C 5000 h to 10000 h100% Authentic Panasonic mademanufactured within a year
I had a problem with the 5v regulator fluctuating on my gen L which caused the temps on the bed and hotend to fluctuate by about 3-5 degrees. An ultra low ESR cap connected to a 5v and ground pin fixed that.
Like you said its a good idea to filter the vtx power source. That's probably what the CAP port is for (there is a CAP+ and CAP- right?). Capacitors absorb voltage spikes and act as a filter. Use a high capacitance low ESR cap like this one
It's uncommon for VTX power sources to require 12v. If you use a modern vtx like this you can just run it straight off the battery without a BEC, with a cap attached in parallel ideally.
Boy oh boy...that was a lot to digest.

I had seen a video or two or more that suggested using the buck converter on the Unify Pro 5V. Another poster had mentioned that the FC should be ample enough to serve as its own buck converter, minimizing any voltage spikes. With my limited knowledge, all I can think is: "well that sounds right." But I surely don't know whether it actually does make sense to implement these additional measures.
