We've given all sorts of toys to my 5 year old over the years
He has a Spider-Man action figure he's never touched, a My Little Pony he's never played with, several stuffed animals he's held onto for about a day each with a pink flamingo being the only he's returned to several times
He had a Baby Shark obsession (not really leaning towards boys or girls?), he was into Peppa Pig last year but wouldn't touch the toy he got for his birthday
Now he's all about vehicles - cars (including a big pink convertible that's something like a Barbie car), construction and emergency vehicles and helicopters. He easily has over 100 of them ranging from Hot Wheels/MatchBox to a battery operated ride on police car
I guess cars are more boy orientated, whenever we see another kid at the playground with a vehicle it's usually a boy
TL;DR - If my son likes the toy (99% of the time being a vehicle) he'll play with it and hold onto it until we head to the register if we're at a store
