German vs. French vs. Spanish

I took one year of Spanish in middle school, and one year of Latin and then two years of Latin in high school and am planning on taking my 4th year of Latin next year (Junior Year).
I am also planning on taking another language class at a community college near me.
I’m only fluent in English, but I’m also very good at Latin, and I speak a little Russian and a little Spanish.
Which class (German, French, or Spanish) do you think would be the most useful, fun, and easiest for me?
Thanks

I would say to take either Spanish or French. Did you like Spanish when you took it?

Not enough info is provided. Which culture interests you? Which country do you plan on visiting in the future? Which language provides you with opportunities to use it outside the classroom?

With a background in Latin, probably Spanish.
