I'm probably one of the best examples of good players playing dozens of turn-based games alongside ekmek yok so I'll try answering that (though I don't play at all these days, I used to have up to 30 simultaneous games while 650+).
1. Honestly, I would rarely note anything other than cards I passed or skipped. Sometimes an occasional reminder to claim a milestone just to be safe because I was blundering those a lot at first, but with experience I think I don't even need it anymore to remember to claim when needed.
2. I wouldn't go as far as min-maxing everything multiple gens ahead by doing probabilistic calculations, but I definitely could take several minutes calculating the implications of a dubious draft buy. I assume most of my opponents, even 500+, were not doing the same. I think most players playing turn-based do it because they like having 1 or 2 moves to make when they have 5 minutes to check their phone, so they don't actually use it to make super calculated plays every time. And to be honest, I would also play a ton of moves on my phone without much thought too sometimes.
3. I don't think turn-based and real-time have different game quality given players of equal elo. I do think that a 600+ playing turn-based for the first time will make more blunders than in real-time, but the opposite is true as well. I make so many silly mistakes in real-time because the flow of the game prevents me from carefully thinking about everything.
4. I think peak elo might be easier to reach by tryharding turn-based games because it's hard to fully focus for the entire duration of a real-time game, while in turn-based you can chose to only play when fully focused. I don't think it's because opponents would play worse, as said above I don't think the game quality varies at all. I completely disagree with you stating good players will play near optimal in real-time. It is much more true in turn-based imo. You just don't forget important information in turn-based even after two days, either because you're used to this mode enough to keep track, or because you've taken note of it.
5. It's both hard to estimate and very fluctuating. I would say between 30min and 2h of thinking time depending on the game, with some occasional outliers. Sometimes I would spend like 20 minutes on the starting hand alone. If I'm really unsure about it after 5 minutes I will just move to something else and come back to it later, and it may happen several times before I make my final decision. Same can be said to a lesser extent for drafts picks or other important moves.
And I will say about playing 20+ games specifically that I never thought it was that hard. I could definitely not remember all games, but seeing the position usually instantly brought back the thoughts I had while making prior decisions that led to that situation. Not instantly with the full details, but those would eventually come after analyzing the board/prod lines/blue cards for like 5 to 10 seconds, which is reasonable to me.
I think it's similar to chess grandmasters playing dozens of games at a time. Just looking at the position for a second is enough to remember what their thought process was last time they played it. I think it just becomes natural with experience. If it was an actual disadvantage, we wouldn't have a top 3 player doing it.
