Ideas for toys

I have one 5 year old and a 3 year old boy. Recently I feel like they are so bored of their toys and I would love some ideas of any toys you find your children play with repeatedly or can hold their attention? Feel like they pick out plastic rubbish from the shops and lose interest after about 5 minutes. I’m thinking things like a toy kitchen, magnatiles or any thing similar? I take them out a lot but thinking ahead to the raining, darker weather. Thank you!
