Not sure if I understand your question.
1. If you mean to ask if there
is a difference in the experience for the player between playing the seduction and dominance, then I can't tell what people feel, I can say I invest 100% effort in both and
try to make them unique and enjoyable.
2. If you mean to ask if your actions are tallied somewhere and hidden counters count them, then the answer mostly no. There are some flow where they do affect future outcomes, most notably is if you're being rapey during the Ziruan oasis quest, you won't have the option to recruit Fahda later on but these are few and far between. I wanted to give players real freedom when making their choices and not worry too much about losing future content. Having said that, I do contemplate adding an
optional Reputation system that will affect your strategy game, something like if you have a high negative rep your high Obedience will be more efficient but Morale in the fiefs will suffer and the other way around, if you are generally act like a non-asshole, your positive Reputation will increase and your fiefdoms will be more productive but you'll have to struggle a bit more with restraining the unruly segments of your population. If I do implement the Reputation, your decisions during the quests may contribute to your score.
No, you can put all 5+ in the palace. The veterans here remember when the Wenches in the palace used to be a standard Ren'py menu but it got so big I moved to the interactive yard we have today. I believe that Karder can find me a bigger yard if I need to
