Cinematically speaking, I think you have to include the F65 on any list. And I would rate it right next to the Alexa. Ease of operation would push it down a bit, unless you have a big crew.
I do a lot of handheld work, and to me, it's all about ergonomics and simplicity, so that pushes the Red cameras down the list. I tried all kinds of rigs on the Red One, and nothing was ever comfortable. Haven't work with the Epics, but even though they are lighter, they look like it will be the same. The F55, even though not as cinematic feeling as the Alexa and F65, can balance quite well with the right gear, and it's relatively easy to use. The F65 did not have bad ergonomics, but it was quite the monster on your shoulder.
Also missing from this list are the new Panasonic cameras, the Varicam 4K and the LT. These cameras will be contenders, as their image is very cinematic, the skin tones are second only to the Alexa ones, and their low light capabilities are nothing to sneeze at (since you are shooting indoors, that can be very helpful). They are also not bad on the shoulder. The big sister can be a little heavy, but it's a "good heavy".
Regarding the F5, it's almost identical to the F55 physically, and the image is decent, but the F55 is on another level for skin tones and feel. I would consider the F5 image more of a video/news quality than as a cinema camera. The F55 is very close to the F65, but you can definitively see a difference.
Since you said to ignore price, I'm not going to bother with the others on the list. Don't get me wrong, I have seen beautiful images from most of them, but if money is no object, then go for the best.
If I was to make my list, cinematically speaking, it would be:
Alexa
F65
Varicam 4k
Red Epic
F55
the rest
but it's not set in stone.
