If you postulate a species that has solved item #0 (faster than light travel or very near light speed travel) then you have also postulated a species that is likely technically advanced enough that #1-5 no longer matter (i.e., they have found technical advancements that make the other points no longer relevant).
I.e., #1 -- ease of manufacture. A FTL species likely also has some technology similar to Star Trek's "replicators" -- and once said species is capable of assembling products by positioning individual raw atoms, difficulty of manufacture of a product onboard a space ship fades away and becomes little more than a raw supplies (you need the input raw materials) problem.
I.e., an "atomic" (as in placement of individual atoms) 3D printer allows for most anything to be assembled (provided one has the CAD files for the 3D printer and the required atomic materials).
