What humans in "pop culture" now call "love" is just a bunch of neuro-chemical processes manipulated by faceless organization for consumerist profiteering.
What counts is the theological habit and moral act of charity, which has God as its formal object. True charity will lead to that conjugal charity that sees beyond the imperfections and deficiencies in this world (and the physical ones shall be effaced at the General Resurrection anyways) and love the spouse or betrothed for the sake of God and for His greater glory in bringing forth servants and handmaidens for the liberty and exaltation of His Holy Church and that of Christendom.
But the question is if the person in question negotiates away for a lesser candidate merely by reason of the fact that they cannot have better prospects.
To that I answer in the negative: one should not marry any particular person just because of one's comfort or because the candidate happens to be there.
It will be an unhappy marriage if undertaken for that reason.
However, if true charity and Sacramental grace from Holy Matrimony are observed, such things as physical defects don't really matter: unless these cannot allow the physical act of procreation, in which case the marriage will either be radically invalid or it would have to be one in which both spouse take vows of chastity.
