I did play a nocaster a few weeks ago, but I can't really remember much about the shape of the shoulders (only that I loved the guitar).
If it's a quite pronounced U shape that is awkward for you, you can still find fat necks that might be easier. The fatbacks made by Warmoth and USACG are both C shape, so smaller in the shoulders, and the boatneck (super soft V in USACG's case) has even less material there. Those necks are still 1" thick so you shouldn't lose the fat vibe.
Finding some to test out might be the only tricky part.
