I know there's a nice foot cutout in row 6 that I do not believe is present in row 1.
Sat in 1C on an A319 yesterday and there was a cutout on both sides. I'm not certain that this is the case with all of the 319's however.

Now, if United Easy Update works and notifies you in a way you can immediately know, then you can check to see what seat in First you were assigned and if you can move to something better. If you can't, chances are 6F will still be available.
However, Row 1 on the Airbus is not bad, frankly. You can't stretch out as much as Row 6, but you don't need to keep your knees bent 90° and your feet flat to the floor, either.

It can be a bit of a crapshoot when waitlisting for an upgrade. I was waitlisted for the flight yesterday using 500 milers and it cleared about 3 hours prior to departure. I asked the RCC agent about seat options and she only had 1A and 1C. I actually kinda like bulkheads so I was fine with the choices. Given the choice between Y and F I'll take F every time regardless of where I'm seated.
