Also I think Bluetooth doesn't require anything extra if you don't use it in marketing, just classic FCC and similar for other countries.

Last I checked, you can use bluetooth without bluetooth membership but you can not say bluetooth anywhere. 

It's hard not to use the word 'bluetooth' in a user guide that tells users to make bluetooth connection. "click the symbol that looks like a B" is probably a little iffy.  I don't want users wondering why I have funny wording nor do I want bluetooth coming after me.  As Dave would say, that would cumagutsa

Kasper:
Thanks everyone for all the replies.  Lots of good ideas here. 

Audio: This could probably be done without the user even knowing about it which would be great but I think people are growing weary of everything having microphones so I don't want to go there.

I am still leaning towards website based with AP, no app.  It sounds like that is the standard and robust method.  Many good ideas here though, some sound better but not better enough to justify going away from the standard, specially since this is not my area of expertise.    This being my first product (on my own) I'd like to focus on making it solid more-so than fancy.

Have the setup app be open source ("generic" and can be used for any device with a compatible implementation) and have the manual direct users to download that open source app to set it up. Any mention of Bluetooth would be in the app and only where absolutely necessary e.g. prompting the user to turn it on if not already.

How you will make the server infrastructure to work over the internet?

ESP32 and ESP8266 support a feature called ESP Touch, it use only Wifi but it require an application running on a smartphone either Android or Ios, they have samples application if you want to edit it yourself. The idea is that this application will broadcast wifi credentials through the router on which the phone is already connected, while the module will be sniffing for those frames. You can connect multiple units at once using this method.

ESP32 support WPS as well, so a button on the device can be used, sample code can be found in ESP_IDF.

These sound like the easiest solutions for the users but would they be venerable to users' neighbors who are constantly sniffing or other hackers?

I think the frame is encrypted
