Spilled coffee on trackpad and speakers (but not keyboard) of 2012 MacBook Pro. It worked fine after. What steps should I take now?

Liquid damage is pervasive and progressive – your Mac may work now, and may malfunction in a few weeks as a result of the recent spill.

You can try running Apple Diagnostics, but it would be a good idea to contact support.

Luckily, it wasn’t much (iced/watered down) coffee with milk, and most of it went on the keyboard cover so I could quickly get it off. Nothing got on the keyboard.

But a bit dripped down in between the screen and bottom half of the laptop (don’t know the technical term for this). Are the speakers located here? They sounded fine.

A little got on the trackpad as well and it worked fine after I wiped it clean, no stickiness. I’m not sure if any got down in the crack for the 10-15 seconds it was wet before I wiped it off.

I still unplugged it, turned it off, and put it upside down.

Is there anything else I must do?

I don’t have any tools if they’re needed to open it up. Do I still need to take it to Apple, if they’re even open in my state, to make sure nothing corrodes?

Thank you!

I would have robust backup plan in place.

2012 is getting long in the tooth... what are you going to do; if it were me I would wait and see if issues develop.
