This is a two fold question:
1. Design
2. Servicing
Bolt actions are generally more reliable then semi auto's. Less moving parts, etc. More moving parts generally require more lubricants and are more prone to breakage.
The best cold weather rifles can be rendered useless in cold weather. I went hunting with my father two years ago in -45 weather. His Sako (Finnish rifle) had a hang fire (firing pin slowed due to oil in the bolt) and my Weatherby Mark V had a miss fire (firing pin slowed by oil in the bolt and didn't hit the primer hard enough). The second round chambered in my Mark V did fire. Lesson learned, don't excessively oil you firearms or if hunting in cold weather use teflon lubricants which are not effected by the cold.
The same goes with WWII arms. The Germans had Winter Lubricants, but in the extreme Russian cold, they simply froze. They then tried petrol, but even that jellied. The Soviets had better luck with a petrol/oil/alcohol mix which seemed to work well.
Pissing on a bolt might work, but it would eventually freeze pretty darn quickly. You can also work most rifles without lubricants, but it will generally increase wear.
I think all the rifles mentioned would work well if serviced properly for cold weather. I own most of them (Garand, Enfield, K98 Mauser, SVT, SKS, Mosin Nagant, G43). I have used most of them in cool weather (-15) without issues during deer season. All are great designs in there own right.
In real cold weather I would edge towards the bolt rifles and then the semi's with the SKS first on my list (very simple design, with few moving parts).
Extreme cold can have a huge impact of firearms. I read an article on a guy who hunted polar bear in the arctic and the cold weather even caused his trigger to break snap off (metal became that brittle), among other problems (not a word of a lie).
This is one of the reasons that Canada has one series of AK actions that is Non-Restricted and not Prohibited. The Finns improved the AK action/design for extreme cold weather and released the Valmet series of AK actions (The AK action is a semi but also one of the most dependable in the world). Originally rifles like the Valmet Hunter and M78 were on the Prohib list until the Inuit and northern hunters along with some political reasoning convinced the Feds to take the Valmets off the Prohib list, which resulted in them being on the Non-Restricted list. This is a little know loop hole. The only problem is Valmet doesn't make new rifles and the ones in the system generally sell for $3000+.
I think the CZ858 with a teflon lubricant should also work well. The teflon coating has a similar friction coeficient to ice but is dry and cannot freeze. If using it, make sure all parts including in side the bolt are cleaned of previous oils before applying or the old oil will simply still freeze up.
Cheers

, no major "####-on-closing" vs. "####-on-opening" discussion
, yet ?...
I've had my enfield out in -45c no issues what so ever. Also heard somewhere that the Russians used a bit of kerosene in the actions to keep them from freezing. Not sure if this is true. But German manufacturing has always been stupidly over engineered great for when they work but a clusterf__k to repair if sometnig goes wrong. Tiger tank great example leaps and bounds superior to the Sherman but you could piece together a working Sherman from several dead ones. The Tigers all had to be hauled back to Berlin for repair. Hualing a 30+ ton tank from Russia to Germany is a feat in itself.
