The neighborhoods you mentioned are all fine safety-wise.

You can use the Comptroller’s map of shootings as a rough proxy of safety:

For moving trucks, you can get Temporary No Parking signs:

You fill out some forms, and you’ll then have to go pick up the signs yourself. You’ll want to put them up a couple days ahead of time to give people a heads up. If the spot you want opens up you can try a combo of the no parking sign and cones to try to hold onto the spot till your truck comes.

From there…it’s a bit of a crap shoot. Like, if someone is parked there, I think you have to call the police to get the car ticketed (which they may or may not bother to do), then call a towing company. it’s hard to enforce, and usually more trouble than it’s worth.

And if they don’t…no worries. People deal with road inconveniences and double-parkers every day. Someone may get mad. Eventually the task will be over. By the next day it’ll all be forgotten. I think this is a good time to pay for pro movers, preferably locals, and just kinda pay them to have it be their problem.

If you really are forced to truly block traffic entirely on your block, a cone at the end of the block to keep people from turning onto the block and getting stuck may be a good idea.

Definitely check out Washington Square West. It's safe with some really nice parks and walkable to everything.

Look in Rittenhouse, more going on there than the ones you listed, although those are good options too.
