My personal preference is Grindelwald, but either place is magical. I think it comes down to whichever town you stay in the first time, that creates a powerful first impression. Wengen is slightly more compact as well as being car-free which creates a different ambience, particularly at night.
As far as accommodation goes, I always suggest people check out holiday apartments (Ferienwohnung, or FeWo in German) because they can be a lot cheaper than hotels. The only drawback with a FeWo is that a lot of them can only be rented for a week at a time, but if you see something that takes your fancy, just enquire. July is the high season, so it may be difficult. You could always extend your trip😊.
