You only have one school, you don't get a choice.

I mean the 4 types of group you join.

It's give your MC a background, dialogue and cosmetic. Unique quest which barely matter and forgotten.

[Jynn]

One unique quest during the story that changes based on your House

Different dialogue sometimes based on what House you are

The uniforms you find will always be your House colors

Feels weird to see someone who doesn't understand the Hogwart's Houses.... I feel like that says something negative about me more than it does about OP though for sure.

It's almost entirely cosmetic. (A lot of the costume parts will automatically be colored in your house colors / bear house symbols.)

There are a couple of quests where it can become important, but mostly in the sense of where you need to go. (For example, the tokens from the flying keys cabinets, need to be returned to your House common room, the four common rooms are in different places in the castle.)
