Any resistance going from first to second in a healthy transmission is due to mismatch of engine and tranny speed. For instance, if you gently accelerate to 5000 rpm in first and then shift to second, the engine speed will need to drop to around 3000. There'll be resistance if you try to push it in at 4000 or wait until 2000 rpm.

If you go up to 2000 rpm and do the shift and wait a full second, that might cause resistance, but shouldn't result in a grind.

Absolutely correct. In addition, if you can rev match nicely, you don't even need to clutch to shift. Not that I do it, but just one of the things my dad taught me about manuals. As well as double clutching, which I do do. Nothing like that double thump when you get used to it.
