You cannot simply swap the female to male as it won't be compatible with future expansions.
It's better not solder it at all and let the end user to solder if they will use extension boards.
Unfortunately, I couldn't find any 3 or 5 pin female Arduino header. I will give it another look. The idea with the male header was more a compromise, but I see your point here. If we want to ensure future expandability, we need to agree on a standard connector.

But it's kind of preference.
yes, but the ADDA cost also 12€ and more, depending on where to buy. The price is already skyrocketing and my intention here is to find the best price-performance ratio
If the values from the datasheet are true then the Sunon should also run with 21dBA. But I understand that marketing and reality are often two different things. We will see how it performs.
I agree with you on that. I will order the vertical switch from RS as you suggest, but it will also add another euro to the total.
Thank you very much for your feedback! It helped me a lot
