Which 70-300mm 4.5-5.6 VR do you have? There are three currently available: AF-P DX 70-300mm 4.5-5.6 VR (crop only), AF-P 70-300mm 4.5-5.6 VR (FX), and AF-S 70-300mm 4.5-5.6 VR (FX).
If yours is the DX, then it will crop on the D750... you'll end up with about 10MP files instead of 24MP.
If it's one of the FX lenses, it simply won't have as much "reach" as it gave you on your D7100. If you use the 300mm end of the lens a lot, you'll need to look into a 400 or 500mm lens for the D750.
On D750, your 35mm will no longer be a "normal" lens... Instead it will be a very moderate wide angle. And on the FX camera the 50mm will be a "normal" lens, instead of the short telephoto it is now on your D7100.
AFAIK, all Nikon 50mm are FX lenses... so will work fine on a D750.
Some Nikon 35mm are DX lenses... if yours is one of those, it will crop on the D750 too. Other 35mm primes are FX and will work without cropping.
What is it you hope to achieve "moving up" to an FX camera? Your D7100 and the D750 have the same 24MP resolution. If you don't make big enlargements from your photos, you won't see much difference. Well, actually you will when you are looking at your images ridiculously enlarged at "100%" on your computer... but after you've sized it to make an 8x10, 11x14 or to display online, no one else will ever see the difference.
One difference would be that the FX camera will show less noise at high ISOs... which can be helpful in low light conditions.
Of course, with an FX camera you'll have somewhat fewer lenses to choose from, although there still are plenty in the Nikon system. FX lenses will tend to be bigger and more expensive than DX lenses, too.
And the D750 has a 1/4000 top shutter speed and a 1/200 flash sync (vs 1/8000 and 1/250 on your D7100).
