I'm torn on what to do: Amsterdam for 10 days or split with Paris?

I’ve just arrived in Sweden to visit family and have about 10 days free, so I’m thinking of doing a short trip to either Amsterdam or possibly Amsterdam + Paris.

For the Netherlands, I’d really like to explore Amsterdam properly and visit places like Zaanse Schans and other nearby towns. I’m wondering if 5 days is enough to comfortably see the main highlights (canal tours, museums, day trips etc) without it feeling too rushed.

I know the Anne Frank House is usually booked out well in advance, so I know I won’t get in. Is this level of advance booking common for other major attractions in Amsterdam and the Netherlands or is it mostly just that one?

Is it still worth it even if I’m planning quite last minute, since I'm planning on going around 10th June?

Accommodation wise, I’d prefer to stay fairly central in Amsterdam (and Paris if I do go), but I’m open to nearby areas that are still well connected and a bit more affordable and safe if anyone has recommendations.

If I do extend to Paris, I’d also be interested in thoughts on whether splitting 10 days between the two cities is realistic or if it would feel too rushed.

Any itinerary tips for both places or general advice would be really appreciated.
