Quick notes:
You actually can move windows around, they just don't remember their new location. On the other hand, I don't see the font problem you're seeing, I actually find it more simple compared to the other screenshots you posted (they had lots of colorful windows with various font colors and sometimes style) I believe FFXIV is better in a way that is simple and direct.

Hint on avoiding using the menu every time you wanna do something (not the ideal solution, I believe SE should work on it, but it works for me as for now): assign keyboard shortcuts to the things you regularly use, like Journal (J), Equipment (P), check other player's char (Y)...etc. It made my life easier.
