Re: Ensuring a flicker free gaming experience

Slow transitions: Yes
Flicker from slow transitions: No
Slow transitions do not reliably correlate to flicker. Also, the faster the transition, the more likely flicker will become worse (e.g. inversion artifacts, etc). When a pixel is slow, it's harder for the pixel to flicker harshly. Faster TN monitors have more inversion flicker than slower IPS/VA monitors. In short: Flicker and slow transitions may exist at the same time, but they generally almost are never the causes of each other.
You are currently asking deeper questions that is mainly only asked by those people who get eye pain from most displays (ouch to CRT, ouch to plasma, ouch to DLP). But you've already mentioned you're okay with many screens. So I think you're overanalyzing at this stage. Find a PWM-free display with modern ergonomic features (e.g. low blue light, etc) and be done with it. You can even get one from Amazon -- they have good money-back guarantees.
Regardless, I guarantee you -- relatively speaking -- a PWM-free backlit LCD is among the most flicker-free screen technology of any kind currently on the market (LCD, OLED, CRT, DLP, plasma, whatever) -- of all of those, LCD has the least flicker issues of them all, and of any flicker issues, only affects the ultra-sensitive type people who get instant, immediate eye pain from staring at CRT/plasma/DLP/etc. (usually less than 1% of population). And even so, since you have not indicated a problem looking at plasma, your eye issues may have nothing to do with flicker.
Usually, flicker is bad. But it's not always the case for 100% of humans worldwide. For some of us, there is motion blur eyestrain. The the use of NVIDIA ULMB (Ultra Low Motion Blur) uses intentional precisely synchronized backlight-flashing at 120 Hertz (like a 120Hz CRT) to fix the LCD motion blur, as seen in 60Hz vs 120Hz vs ULMB. You can see things like the old LightBoost testimonials from year 2013 of people absolutely loving a 120Hz strobed monitor flashing in their faces (LightBoost intentionally strobe-flashes at 120Hz). Obviously, you're probably wanting to avoid all that anyway, but it goes to say, what bothers person X doesn't always apply to person Y.
Also, you're not one of those unlucky people who get eye pain their entire lifetimes with all displays? The kind where you get sudden stabbing eye pain the moment you stare at a CRT/plasma/DLP/etc. [rheoretical question too, because you've already answered you've been fine with lots of screens]
And I've already given you advice (go for a PWM-free IPS 60Hz LCD) which solves the vast majority (often >99%) of all the flicker-related issues of an LCD display. And now, you're still asking these questions to try to eliminate the final 1% of the remaining faintest-gentlest-modulations of an already most-flicker-free-possible display technology category (PWM-free IPS 60Hz LCD)? [rheoretical question]
