Struggling between RF USM and STM lineup as an amateur

My wife was very happy with zooming, etc. I found myself sticking to 50mm almost whole time, as if I wanted to prove myself that RF 50mm F1.2 would also be a good choice. On one hand, I know that I can still buy this superior prime lens, now or in the future. Choosing RF 24-70mm F2.8 over RF 24-105 F4.0 had me thinking, that then there will be less stops difference to the prime (F2.8 => F1.2, instead of F4.0 => F1.2). It this a false attitude? And having bought RF 24-70mm F2.8 didn't render RF 50mm F1.2 less worthy to add in the future? It's more of attitude problem, so I would be happy to read your insight.

The 50mm will give f/1.2 at 50mm only. Not at 24-49, and not at 51-70/105. So the f/2.8 zoom will still give you one stop more light at other focal lengths, and especially the wider ones are important. At the same time the weight of the f/2.8 zoom is still manageable when going for a walk with the wife, unlike the 28-70 f/2.0 USM. That's the value of an f/2.8 standard zoom. Perfect compromise. Keeps things simple.

Simplicity helps to capture the right moment. Woman will always pick the picture with the perfect smile, no matter the DOF, bokeh, even focus, etc.  The immediacy of a zoom often wins from having to zoom with your feet to capture the perfect expression. You'll also need less time to spend on using the camera to get some of these moments.

Look, I love bright primes, but zooms are more practical, and having a zoom capturing twice the light is even more practical.
