Regarding the P1797 fault code, I think this is the same component I've been having intermittent problems with on our Journey (62TE transmission). It's not a neutral safety switch, but is now referred to as the TRS (Transmission Range Sensor). Unfortunately, it is deep inside the transmission requiring the pan dropped and valve body removed to access. Probably looking at 2-3 hours labor at over $100/hour (maybe more).

I would advise having a properly equipped shop or dealership confirm the diagnosis first. Mine has never been hard to get out of park. I just had no start issues. Whenever the no start situation occurred I could move the gear select to neutral and it would start up. Your symptoms sound more like a hardware or physical problem - maybe a brake interlock problem or a dragging parking pawl? Perhaps the parking pawl has been damaged? Again, I recommend a competent shop or dealer to do diagnostics - plan on an hours labor charge.

I'm not sure if the ECS is related or not. My Journey owners manual indicates if the ESP (Electronic Stability Program) light is on (other than at start up momentarily) a malfunction has been detected.

The ECS/ESP button you refer to allows you to partially turn off the electronic stability control. The ESP (or in your case ECS) light will be on to indicate this. Consult your owners manual.

FWIW - the TRS lists as a relatively inexpensive part - about $40-$60. The problem is the pan and valve body have to be removed for R&R. Then you have to figure in labor costs and fresh fluid.

I cannot trust the dealerships in my area. I drive taxi and a taxi driver is the last person they want to help. The reason is because all the taxi drivers before me always would go to dealer, get the diagnostics done and find the problem and take it to their personal mechanic to fix it. so far, i have had 2 bad experiences with dealerships close to me.
Please note I said "properly equipped shop or dealership". The choice is yours. The problem you may run into is not all independent shops may have the diagnostic tools at its disposal that a dealership will have. YMMV.
