...No matter what some people think or use it for 24-70 is not a standard zoom for aps-c. For that it is just too limited at the low end.
35mm is a great focal length to start with - if it fits with your intended use.
I've never said 24-70 is a standard zoom on APS-C, nor am I now. I'm just stating that
depending on your intended use cases, a 24-70 or even a 28-75 can offer a very versatile FOV range on an APS-C camera. It's only
"too limited at the low end" if your intended use is wide angle photography, where a 17-50 would be better suited. For the portraiture example I gave previously, a 24-70 or 28-75 is hugely versatile on APS-C, way more so than a typical APS-C "normal zoom".
Of far greater importance to the OP, I think, is the difference in FOV when moving up to full-frame with the same lenses. Once you get used to a lens with a particular field of view on APS-C, that same lens on full-frame will feel very different and may not seem as useful any more - especially for the same subject matter. We've seen more than a few instances of people who loved the FA31 on APS-C, but found it to be too wide-angle in view on full-frame.
