I experienced the very opposite problem when trying to install TeX
Live 2020 — the installer used <i>my </i>"wget" in preference to
one supplied as a part of the TeX Live installation suite, and the
installation failed. I therefore think that there is no one "best"
solution — whether to use pre-existing user/system-supplied
executable images, or those that come as a part of TeX Live, and I
can therefore only suggest that there be a configuration file under
"texmf-dist" which defines the default behaviour for each and every
executable image that comes as a part of TeX Live. A user finding
that this behaviour is sub-optimal for his/her system could then
clone that configuration file to the corresponding location under
"texmf-local" and change the behaviour (in the local copy) for those
image(s) that believed to be causing problems.<br>
