9999 is enough and could avoid weird edge cases in nroff et al.

Like @nhooyr mentioned, let's leave the extra options out. Users should be able to achieve this via au FileType man setlocal .... (And if that doesn't work, that needs to be fixed rather than making shadow options for everything)

what 'linebreak' setting is needed, if any?

When nroff justifies a line, it fills the line with whitespace to meet $MANWIDTH. With $MANWIDTH=9999, that of course results in nonsense (and behaves poorly with 'cursorline' option). To work around that, instead of trying to hard-justify the lines, just replace the mega-whitespace with a fixed size of 10 spaces. Perhaps N/Vim needs a "soft justify" feature?

fix: set manwidth to not exceed the window width If we set the MANWIDTH variable to a value wider than the window, the contents wrap and formatting breaks. A more sensible way to handle this is to interpret MANWIDTH as a maximum width, but to set the width to the window size if smaller. See also: #9023, #10748.
