From a usability aspect, in my view this combination is the best one available for Pentax. However, ...

... if you are interested in using your studio strobes and speedlights in combination or just owning a single triggering system only (i.e., use one and the same trigger for all your lights), the Godox system is probably a better choice. Sadly, Cactus' attempt to launch a more powerful lighting solution (RQ250) failed with a Kickstarter project that missed its funding goal. So with the Cactus system you only have the RF60X and third-party speedlights (per V6II receivers). You can also easily trigger studio strobes, etc. but you will neither have remote power-level control nor an HSS option for these.
Godox offers speedlights, compact but powerful off-cameras lights (AD200), and battery-powered as well as cabled strobes as part of one radio system. I find the Cactus V6II easier and quicker to operate than the Godox XPro-P, but the latter also has some advantages and you should be thinking about whether you want to maintain two separate trigger systems (which could certainly be made to cooperate with each other, though).
