I always shoot RAW and never JPEG. While I'm waiting for Capture One RAW capability for the Z7 I'm shooting both. The JPEG's look awesome and it got me wondering if the NEF's will look the same as the JPEG straight out of the camera? Will the mid range sharpening affect both the NEF and JPEG's?

No they won't. NEF files are RAW files with no picture style applied and no in camera processing. JPEGs have whatever picture style and a bunch of other camera set-up parameters applied to them. Also JPEGs are compressed with lots of permanent loss and are only 8 bit per color. If you open a JPEG and resave it as a JPEG, everytime you do that, you further compress the file and throw away information. If you like the JPEGs, first save them as a TIFF to prevent file degradation when you resave the file. Just google JPEG vs. RAW - there are literally books on this.

Actually, JPEGs are superlossy. Hell of a typo!

A great photograph is absorbed by the eyes and stored in the heart.

Yes, very much so. Typo on my part.
