I would like some opinions on the advantages upgrading to either a Nikon D500 or a Tamron 24-70 g2.
I currently have a Nikon D7100. I have a macro, a 10-14 wide angle, and other lenses. I use a 16-300 Tamron for most of my pictures. I seem to use it mostly in the lower ranges. I do not have a 2.8 zoom. I also take almost no sports or action pictures and usually use a tripod if possible.

Hi Terry,
If you shot sports, wildlife or other action the higher performance AF, faster frame rate, bigger buffer, etc. of the D500 might make sense as an upgrade. But you say you don't shoot anything like that, so would probably not be served well buying that camera. In fact, the D500 is 21MP, while your D7100 is 24MP. The D500 has a newer sensor and is likely better for high ISO, low light work. But in all likelihood you'd see little gain from a camera upgrade.
But from your description, I also don't see much or any need for a bigger, heavier, more expensive f/2.8 zoom. You also don't need a full frame capablelens, like that 24-70mm (Tamron calls their full frame lenses "Di", instead of "FX"). You can probably find equal or bettery image quality in a smaller, lighter, less expensive DX lens.

probably would benefit from getting something better than the Tamron 16-300mm. Most of those "do it all" zooms simply don't do much particularly well. They can be "okay", but compromise in a lot of ways and are primarily "convenience" lenses. Generally speaking, a more modest range "standard" zoom give better performance and image quality. I do not know the Nikon system well enough to recommend, but would bet you'd get the most bang for your buck with something like:
AF-S DX Nikkor 16-80mm f/2.8-4E ED VR
AF-S Nikkor 24-120mm f/4G ED VR
AF-S DX Nikkor 18-140mm f/3.5-5.6G ED VR
If you felt you needed a longer focal length, there are:
AF-S Nikkor 70-200mm f/4G ED VR
AF-S Nikkor 70-200mm f/2.8G ED VR II
AF-S Nikkor 70-200mm f/2.8E FL ED VR
AF-S Nikkor 80-400mm f/4.5-5.6G ED VR
AF-S Nikkor 200-500mm f/5.6E ED VR
Notice that all the above are telephoto-to-telephoto zooms with 3X to 4X focal length ranges (as compared to 16.66X with your 18-300!)
I've never heard of a 10-14mm lens, such as you mention... So I am not sure what you have for wide angle or if it's something you use much or need to upgrade. Nikon just introduced a very affordable AF-P DX Nikkor 10-20mm f/4.5-5.6G VR. Their other ultrawide DX lenses are pretty pricey: AF-S DX Nikkor 10-24mm f/3.5-4.5G ED and AF-S DX Nikkor 12-24mm f/4G IF-ED. I don't know that those are any better than some third party alternatives that cost a whole lot less, such as Tokina AT-X 12-28mm f/4 DX and AT-X 11-20mm f/2.8 DX. There also are Tamron 10-24mm, Sigma 8-16mm and 10-20mm.
Notice that all these ultrawides are wide-to-wide with approx. 2X range of focal lengths. Few have f/2.8 apertures, too... most people don't really need large aperture ultrawides and it can cause some compromise in image quality, as well as make for a bigger, heavier, more expensive lens.
You mention macro and other lenses.... but give no specifics. So it's hard to say more than the above generalities. But, almost certainly you'd see more benefit from "better" glass than you would from a camera body upgrade.
