I kicked the tires on Elvis a good while back but am unaware of any
special blind-friendly mode. For all of the console-based editors,
the accessibility usually relies on the accessibility of the
terminal. Though there may be features that, if enabled/disabled
might make them a bit more screen-reader friendly (such as over-draw
repetition when removing a background highlight and highlighting some
other text if selecting from a list). You might have better luck with
vim/neovim if you disable syntax highlighting.

NeoVim is a fork of Vim, so they should be pretty close in all
respects, with NeoVim providing a few more cutting-edge features.

Both support a variety of completion methods. The easiest one is
using control+N and control+P ("next" and "previous" matches) which
searches a variety of places for words that start with what you've
already typed. Where it searches is controlled by the 'complete'
option, and by default searches the current file; then buffers open in
other windows, non-open buffers that are loaded, then unloaded
buffers; then any "tags" files; and finally, if you're using a C-like
language, any included files. Those defaults work pretty well for
code, but are less useful for prose where you might want to add a
dictionary or thesaurus file to that search. For that, you can read
further at
:help 'complete'
where you learn you could do something like
:set complete+=k
to include your system dictionary in the search path.
Control+N and control+P are the easiest to pick up. From there, in
insert-mode, there's a secondary "completion" sub-mode that allows
you to be more fine-grained in your completions. You can read up on
the various varieties of completion at
:help i_CTRL-X_index
When coding, I use the "line completion" (find another line that
starts like this one and type the rest of it) which is control-X
followed by control-L (then control+N/P to navigate those matches
next/previous). I also use the control+X followed by control+F to
complete with existing file-names (saves me from copy/pasting the
file-names).
For prose, I use the explicit "complete this word from the
dictionary" which is control-X followed by control+K (again,
using control+N/P to navigate next/previous matches).
There are other completion features that allow you to get your
completions from a custom function, so you're basically unlimited in
what your completion does (some add-on scripts are
programming-language aware and will complete contextually). There's
further documentation on that at
:help complete-functions
Hope this helps you get started. If you have further questions about
vim, I'll try my best to answer them, but the vim-use mailing list is
also a friendly place with lots of folks who like to help.
