We had an '05 Murano SL, which is different from the SE in it that it got slightly softer suspension tuning, smaller wheels and no 'gear simulation' for the CVT.
It might be a little on the larger side if you're look at compact CUVs. It's built on the Altima platform. Definitely a mid-sizer. Lots of room in the back seats. Luggage space was less than I expected, but we managed to fit plenty of stuff in there.
If you want a CUV that makes you think you're driving a car, then you should check it out. But if you want a CUV that makes you think you're driving a SPORTS car, then get a wagon

It is a very competent handling machine, but a high center of gravity is a high center of gravity.
One thing I liked about it was that you got a lot of goodies for the money. Our FWD SL had every thing except for nav and it came in around 34k, IIRC. Xenons, headed seats, keyless entry and start, power everything, upgraded stereo.. the thing was
decked out.

The interior was definately nicer than a Z. The design of it was really well done. But there were some material choices that clearly said "cost cutting". The important things; the parts you touch and use everyday had a nice quality feel. But tucked out of sight was some really cheap looking plastic.
The Murano had a nice quality feel to it, but it was NOT "premium". The difference is in the details. There was road noise. The doors felt thin and light. A good example: the seat heater switches were parts bin Nissan. They felt reasonably solid and clicked into position with positive action. But they didn't have the rubber coated, ultra dampened, precision finished feel that you'd get in say, a Lexus or an Audi.
In '06 the 1st gen car got a slight facelift and mild interior upgrade, so keep in mind the plastic issues definately got looked at in later models. The 2nd gen car is much nicer inside.
And personally, I think it is one of the best looking CUVs out there.
I haven't driven a CX-7, so I couldn't comment on it.
Drove a CX-9 though, and that was an excellent vehicle 👍. Huge though. Much larger than what you're looking for.
Going to be hard to get those for ~$25k.
