I don't know if you already know of this or not, but FE Shadow Dragon and the Blade of Light is coming to the Switch in English for a limited time. I know you mentioned you wanted to try out the older games officially, so luckily that chance is coming December 4th! I know I'm going to get it just to play through it again, but this time with portability.
Funnily enough, I've been in the middle of a playthrough of Fates: Birthright, and received a few free gifts and birthday wishes from my companions at my castle grounds today. That was an unexpected surprise.
