In the US, all governmental web sites are required to be designed to accommodate vision-disabled persons. Note that this does not mean only person who have no vision at all. All types of vision impairment are considered disability for the purposes of this regulation. Also, any government vendor agrees to the FAR's, which would generally mean that any site that is of a company receiving government funding or doing business with the government must follow the same regulations.
So, see more you asked Option 1,2,3 or 4. Accommodation is easily done with Option 3 for browsers and can be done in the template. I'd like to see that added to the Dolphin-supplied templates.
As for the other options. I would think that this goes beyond a simple mobile vs. desktop paradigm. Everything from kitchen appliances to televisions are being net-connected these days, mostly using Android (vs. IOS). Apps are appropriate for these devices. Many people do not ever launch a browser to type a URL in the box. Even if the 'app' is simply a bookmark which tells the browser to go to a site, people are getting accustomed to downloading the app for the things they want to see and just clicking. Option 4 makes sense here.
I may consider this a big pain in the behind vs. just typing in the URL or clicking a bookmark, but tell that to someone who wants to check your site from their refrigerator door! Like it or not, you must have apps and that means creating them for each type of device or OS.
The catch for me is that my site is for a small charitable organization that has a $0 budget. This means that I donate my time and any software necessary. So, what I'm finding is that I keep hitting my head on the licence restrictions because I can't buy Prime to give to them (or, mostly the add-ons they need).
The Catch-22 in this is that the site, by its nature, attracts a lot of people who are not at all computer literate and often using the cheapest, simplest devices to access it. These days, that means Android devices and small screens. I have yet to find a good way to serve this population with the free version.
