On dating apps I see something really smart. For hobbies you just list 1 thing of interest, follow by a sport and then cooking. Every normie does a sport once a week and everyone cooks daily, so it's an easy way to sidestep the hobby interrogation.
I can basically say: my hobbies are reading, jogging and cooking. Which is a pretty normie answer (instead of saying I ldar) and then normies might just leave me alone. They are the 3 hobbies of mediocrity in case you need to wageslave.
