Struggling between RF USM and STM lineup as an amateur

Hello,

I guess, I'm expecting your acknowledgement. I am just afraid that without this sweet RF 50mm F1.2 I will lose something, some important detail...
If I would go the STM way, there are many primes at the moment:
RF 16mm F2.8
RF 24mm F1.8 Macro
RF 35mm F1.8 Macro
RF 50mm F1.8
RF 85mm F2.0 Macro
I even thought about the new R8, which would be even lighter, but it lacks IBIS, so I think that's not a good idea, especially indoors.
The 50mm focal length is my go to lens. Which one should I accompany it with so that it makes sense?
Or should I buy the RF 50mm F1.2 (because USM will focus quicker as my child becomes quicker as well?) and wait for a RF 35mm F1.2 to get the best of the best...?

Thank you for your thoughts

Normally, I go for a lens because it is solving a problem I have with my current kit.  I'm a hobbyist.  Since you don't know why you want the RF 50 f1.2 or the RF 85 f1.2, I would buy one of the budget lenses, wear it out with use, then buy the expensive prime version only if you found your photography is missing something that prime lens solves.

I bought my RF 85 f1.2, on sale, because I liked my EF 85 f1.8 and used it a lot.  The CA from the EF 85 bothered me a lot after using it for a year.  The RF 85 f1.2 gives me better CA control and weather sealing for shots in rain and snow.  Plus, I wanted to use it for a couple of family weddings that were coming up.

My EF 50 f1.4 works fine for what I want from a 50.  Even with it's weak but accurate AF and poor contrast when the lighting is horrible.  I am happy with my RF 35 f1.8 though I don't use it much.
