Ranking methods for [1-X] voters and N candidates

Question

Situation

I must rank N options (N = 54 here, but could be lower or higher) according to X voters (X = 1 here, though I am also interested on the X = 2 case, as well as a more general case).

Goal

Assuming the voters can spend any "reasonable" amount of time to cast their vote (up to a couple hours), what are the ways to obtain a full ranking of options/to compute a score for each options? Additionally, which are those that can also be applied for more voters?
I understand that the case X = 1 can be weird, as a single individual could be assumed to know their preferences, but with potentially dozens or hundreds of options, it is not always easy determining the best one, let alone the full ranking.
One of the ways to cast the vote could then be to do pairwise comparisons and score the options from there.

Current leads

This situation reminded me of the Condorcet Method, though I am not sure of its necessity in the X = 1 case.
Is this the best option anyway? And what about the more general case?
Additionally, if this problem is not related to decision theory but another concept, do not hesitate to tell me, I'll try and correct the question/the tags.

Thanks a lot!

Edit

To clarify:

1. In the case X = 1, the pairwise comparison can indeed rank all options without much difficulty, and the process can be optimized to limit the number of comparison needed. But is it the only method to get an "ideal" ranking? I think so, but am wandering if I am missing something here.
2. In the more general cases of X > 1, it seems to me that the pairwise comparisons could only take us so far, but that we need another system to determine which option is "the best". In particular, pairwise comparisons can give us the rankings for each voter, but combining the rankings could be tricky. As far as I can understand it, it seems like a ranking combination issue (which seems like what @lulu's comment pointed to). Does the evoked standard voting schemes methods relate to Borda/Plurality/etc.? If not, which are they? In order for me to properly research them and their advantages/drawbacks.
