All the usual, commonplace stuff, I'd think...

An aquarium date, a planetarium date, a walk and picnic at the park, dinner out somewhere nice, working together on making dinner together and watching romance movies or anime at home, amusement park date with a ferris wheel ride, playing at the beach (I can't swim!), maybe even a little book club or manga club type deal between us...

Anything else is more specific, like "them standing up for and protecting me when I'm getting harassed," or "being able to show me their undivided attention during a date, even with their phone getting lit up," or "stargazing together at the Mauna Kea Observatories," going traveling in general...

I dunno, I feel like I'm kinda boring!
