Launching far off the equator makes it more difficult and is therefore a bigger technological achievement.

The selection of launch site takes the orbital inclination into account.

The "Onward and Upward" cube sats were deployed to Sun-synchronous orbits, with a roughly polar inclination.

Similarly, launches from USSF Base Vandenberg take a southerly trajectory, so it can be used for orbits like that.

Rocket launches from continental Europe have been challenging because of the population centers, and the unpopularity of things exploding over their heads, and falling on their houses and businesses. USA and Russia have some quite ideal sites that avoid flying over populated areas.
