Actually, it's more correct to say that the Hausman test fails to
reject the random effects estimation. Both fe and re are OK, but the
latter is more efficient.

This is possible only if you are able to do an estimation of the
model in which you instrument your potentially endogneous variables.

That depends on lots of things, not the least of which is the tastes
of the referees you are blessed with.
