The command-line window can be in normal or insert mode just like any other window, it is NOT a special command-line mode. Command-line mappings do not apply to the command-line-window.

Thanks! 1 & 2 solved the issue.
I was getting some errors when using
exe "normal <c-f>"
in a function so I decided to try to make two maps. Here is what I will
do at the end:

fun! s:SearchCmdWin()
" Adjust <c-f> when a pattern is written in the command line.
let line = getline(line('.'))
if !empty(line) && line !~# '^\\v'
call setline(line('.'), '\v' . line)
endif
endfun
nm <Plug>SearchCmdWin :call s:SearchCmdWin()<cr>
cm <expr> <c-f> getcmdtype() == '/' ? '<c-f><Plug>SearchCmdWin' : '<c-f>'

Thanks again,
Marcin
