The RF50 f/1.2 I rented handled the shallow DoF things, but I didn’t encounter many situations where f/1.2 was useful, a person holding a baby rarely fits into the DoF. Unless you go for full body portraits, which enters the ‘I need a larger house’ situation again

If that's true, it would bring us back to the 2nd option with RF 24-70mm F2.8 as universal lens, with no practical need for F1.2, unless I take few stops back, i.ex. to F2, still with better IQ. Not so easy to decide...

I don't take RF 28-70mm F2.0 as an option, because it's a beast (as 85mm F1.2 is). Or... should I? 🤕

The thing about the 50 f1.2 is it is so versatile.

It can do DOF shots at f1.2, and gather dim light like f1.2 does, while still able to adjust to f2, f2.8, f4, etc to get a couple people's eyes sharp at the same time. Same can not be said about the non "L" options. You crank a RF 50 f1.8 open to f1.2 with a pair of pliers, it falls apart. It's not as photo versatile.

50mm f/1.2 is great.

You also get durablility, lens coatings, a hood, UD elements, fast AF (ignore claims that it is slow),

It's all relative, but the 40mm Art is faster, and the 50mm GM is way faster yet.

weather sealing, and edge to edge sharpness with the RF 50 f1.2.

Cries about it being expensive can be mitigated if you have the budget. Cries about it being heavy can be mitigated if you are a healthy adult. If two pounds bothers some, I offer a cell phone for photos as it is hard to beat for being light weight, and far lighter than a R5 with Sigma 40mm (truly a boat anchor ).

The 40mm Art is for indoors at home. For it's wider slightly wider focal length it's a nice addition to a fast focusing 50mm. For portability Canon is simply the wrong brand, you can't blame Sigma for that, as the Sony 50mm f/1.2 GM is the goddess of all 50mm lenses for portability, AF speed & accuracy, and the complete silence of her AF system. The heavy RF 50mm f/1.2 boat anchor can't touch it.

For portability >> go Sony. The same is true for a compact 85mm f/1.4 as well.

Canon is the brand for slow focusing boat anchors.
