Prusa MK3s MMU2s with Octoprint on Raspberry Pi Zero W

I have no experience with Pi computers or Octoprint. I am interested in upgrading my Prusa with the Raspberry Pi Zero W, but I don't know what I will gain from doing so. I personally don't see the value of remotely uploading G-codes, as I am particular about making sure filaments are loading correctly and initial layers adhere properly.

What I would like to gain is the ability to look in on the print, which I can do separate from this system if necessary as I just ordered a Wyze camera. If possible, I would like to tie the Camera function to the Raspberry Pi, weather through a Pi camera or the Wyze camera, but not at the expense of loosing other functions that I currently have with my MK3s MMU2s.

The other main thing I would like to gain is the ability to stop prints if the camera shows the print has failed.

I would prefer not to loose the power failure feature built into the MK3s, which I think I will retain as long as I print via SD card. Is there other controls I will acquire with Octoprint I am unaware of? Will I still have the full control advertised on the Octoprint's website when printing via SD card (Pint job progress, GCODE visualizer, temperatures of hotends and print bed and adapt them on the fly, Move along all axes, start, stop or pause current print) or are these only available when printing via Octoprint?

I know most people feel it is better to upgrade to a Raspberry Pi B3+ or 4, but I would prefer to leave my printer as close to the manufacturers recommendations as possible, hence why I would prefer to use the Zero. I have tried to determine exactly what Raspberry Pi Zero W is capable of, but I have mostly been met with "Don't use it". That is fine for someone who is looking to get full capabilities out of Octoprint, but, at this time at least, I am not interested in the full spectrum of capabilities.

You will make your own decision, but be aware Prusa recommendations are not always the best.

At least read this page by the Octoprint organization:

Especially of you want to add Camera+Streaming the Pi Zero W is not recommended. There is a reason why people are saying "Don't use it". In most cases they tried it and upgraded later to Pi B3/4 because Pi Zero W is only usable for uploading and printing (text based processing).
