Ok, so got a handful of DLC. I'll say for what games and how soon you can access in the in-game DLC shop for anyone wanting to know what they have to do to access it.

Fire Emblem Echoes: Shadows of Valentia - You can access the shop right when you reach the world map, which you get to within an hour of playing.

Yo-kai Watch 3 - This one doesn't actually have a DLC shop but if you buy the game digitally you're given a code to use. However, this one's annoying to do because you can't access the code redemption until about 2 hours of playing, probably sooner if you speed through it. There's also a little mistake on Nintendo about when you can redeem the code. The redeem instructions will say that you need to clear chapter 2 to redeem the code, but you only need to reach chapter 2 to be able to redeem it.

I also saw that there's another gift download option in the game but it didn't bring up a connection to Nintendo's eShop server like usual whenever you buy any DLC. So this one is likely Level-5's server and may still be available after shutdown. I recall hearing that the Professor Layton vs. Phoenix Wright DLC works the same.

Mario Golf: World Tour - Just need to get past the how-to-play tutorial when you first start the game and then you can access the DLC shop in the main menu.

SMT IV and Apocalypse - Can access immediately upon starting up the game at the main menu.

And it looks like my own copy of Persona Q doesn't even read (I'm hearing this was a common problem with first prints of this game), and since Atlus is being stubborn about putting their games on-sale one last time, I'll have to use some other way to play it.

Persona Q2 - This on the other hand works fine, and much like SMT IV, you can access the DLC shop right when you start the game.
