Overall, Surviving Mars might be my favorite work soundtrack. Assorted tracks from Stellaris plus the Age of Wonders and Civilization series are also good. Something about the soundtracks in 4X games and games like them always puts me in a productive mood while not making me emotional and thus distracted like RPG soundtracks can sometimes.
Since you like FF, I’d suggest looking into Uematsu’s other works as well, especially Lost Odyssey. For similar ones in the genre, there’s also Yasunori Mitsuda’s work in the Chrono and Xeno series.
