50 is a great focal lenght for family/children outdoors, too tight for indoors but you have the 23 f/2 for that.
I have the 35 and use it for both indoors and outdoors. Works great, a bit tight for indoors sometimes though.
I'd get the 50 if I were you as you already have the 23. Great combo

Few more things to keep in mind about Mitakon 35mm F0.95 II
Aperture ring is step-less, and it has same texture as focus ring and similar rotation effort. It's just named 35mm, but actually it is wider 33mm lens. Out of box focus ring infinity point may not match real infinity and DOF calculations will not be precise. So you may want to calibrate focus ring, which is easy. Some samples may have slight focus play when reversing focus rotation, I fixed that by applying some extra grease to helicoid. I'd recommend to check other pictures taken with this lens. Some samples have front naming plate not secured tight, simply screw it in CW to proper secure. When aperture is wide open and you shake the lens - it is producing moving noise inside - that are aperture blades, and it is normal.

1. Not sure about Mitakon, but any adapted lens reads F1 and as all MF lenses have marked Aperture ring you always know your settings.
2. For decades, decades and decades MF lenses were the only option for all types of photography. I shoot film a lot, so I shoot MF and have no problem with street photo.
3. The only condition you may have issues with nailing focus on moving subjects is darkness, when the SS falls lower then 1/60 or 1/250 depends on moving speed.
That technique called Zone focusing (a lot of explanations and youtube videos). You need DOF calculator ( https://www.photopills.com/calculators/dof ) and to remember how far is 5 and 10 meters away is.
Let's say you are shootig during the day and going to capture some scene at least 10 meters away (everything closer then 5 meters with 35mm lense I would consider "street portraiture"). Usually street photography assumes planty of DOF so it's F8 and more. Thus our calculator said that everything from 4.34m to infinity we would have in focus.
 

So you select 10m and F8 on your lens and don't bother about AF any longer, just correctly estimate 10m distance - plus/minus 3m. Do some practice. )
Another scenario is the low light conditions when you need to open your lens. But even with F2.8 you will have almost 12m of DOF.
