soon-to-be first time 3ds owner! any game suggestions?

what the title says! my partner just bought me a 3ds xl that arrives in a week and it'll be the very first i've ever owned; i had a ds lite and a dsi growing up, but i was playing mmos and other pc games by the time the 3ds came around.

he has some games he wants me to try out (namely fire emblem) but i plan to get a 64gb sd card and wanna download a handful of games. i'm open to just about any genre, do you guys have any suggestions?
