As far as i understand this? You want it on Ryzen Balanced, no matter what, where or when;
What changes are the settings in said power plan:
- If for example you don't use dedicated software (say Ryzen Master) and have a BIOS all core-OC, ideally you max out core speed and power allowance, disable power savings, etc;
- If you do make use of PBO for example or any other software-related feature, you want to keep both core and power settings at default.
The reasoning has been covered here and there, but in short, the less power your CPU is currently consuming (and therefore the less heat it outputs, both come into play), the higher it will shoot up when PBO kicks in and/or the longer it will stay there, hence the above. Inversely, when you have a fixed frequency all core overclock no matter what, you've nothing to gain from any of these "opportunistic boost" features, they won't even be activated for you. So naturally, the higher you keep its cycles, the better. So again Balanced, but with everyhting maxed out or disabled accordingly.
Of course there are two further factors one needs to consider, one being unecessary power draw and the other the actual (read: tangible) use of a steady 4200ish overclock. I won't go into either, as frankly it's more of a stance thing than anything else.
* small note here as i see that "1903" mentioned a lot. All it does, all it does, is ensure the cores speed up or down a touch faster, or more strictly speaking, that there's a reduced latency between the instruction to modify frequence and its execution. Useless in the first scenario (stable all-core OC) and of minimal benefit in the latter (PBO) as has been shown by actual testing. Furthermore if not already evident, nothing to do with the NUMA/UMA-aware issue in non-monolithic designs of Windows Scheduler; that remains broken and equally frankly? Slightly on purpose, lol, but that's a different topic. Don't rush to 1903 and the new full screen ""exclusive"" headaches -which btw can no longer be disabled- unless you really need to, aka know what you're doing. Newest is not always best.
