If you know someone well enough to bring them a homemade meal, why not just ask them what they'd like?
I'm pro tuna-noodle (reminds me of my childhood), but wouldn't want a lasagna as my bestie makes baked ziti and there's only so much tomato-sauced pasta I can eat in a week.
These specifics are gonna be highly variable, so if you really want to be of service to this particular family, talk to them. You can give them a list of 5-10 suggestions and then let them cross off what they don't like and write in what they do if you want to take some of the pressure off.
