Depends on how you construct these spectra.
Like the first approach which gave the name was apparently just to look at the sitting order in the French Post-Revolutionary parliament. Where people with matching political ideas grouped together and where as a result of that people with conservative, monarchist, elitist views ended up being on the right side of the room, while those with progressive, republican, democratic, egalitarian views found themselves on the left and those somewhere in between ended up being in the center.
That is pretty volatile though. Like after the revolution some monarchists tried to help the king escape and have the other monarchs wage a war against France to reinstate him, which was uncovered and the king was executed. So that the right lost their heads, the center became the right and the left became the far left and so on.
So rather than spanning all the political ideas and ideals, it's rather something that has a time and place and isn't neatly applicable to other nations.
Also if you use those broad categories:
Left Wing" (consisting of secular/ atheist/ libertarian/ egalitarian/ socialist/ globalist etc. ideologies) and the "right wing" (consisting of nationalist/ patriotic/ religious/ conservative/ Authoritative etc. ideoligies).
There are good chances that some of these arguments fit different groups for different reasons or that they change their character over time. Like in it's conception a nationalism might have some "leftist" themes to it like being a liberation movement, empowering the people, creating a new social contract by the people for the people. While a nationalism of an already established nation usually has far more "rightist" themes like ethno-racism and discrimination of un-national people (whowever falls into that group), chauvinism and so on.
So again while listing these adjectives in a given context of time and space can make things better understandable. They usually fail to describe the bigger picture.
For that there also have been ideas of constructing left-right spectra which actually try to aim for mutually exclusive adjectives on each side, so that as a consequence of that, all political ideologies and systems would need to fit somewhere on these spectra.
The standard one seems to be the one ranking the ideologies and systems according to their usage and acceptance of social hierarchies. So are there rulers and ruled or are people of equal power and importance. Which at least in theory lets you place all systems somewhere in between those.
Though the more you go towards purely descriptive methods the more you lose the ideological motivation of these different groups and just because you can map them on a spectrum doesn't mean that the scale is linear, like again people can support the same measures for vastly different reasons and that can make a huge difference.
So this idea:
Now suppose a true left wing ruler would do. They will tell to do a lottery for which 10 people would get the food. So that nobody gets more priviledge than the other.
A true right wing ruler would stratify the people based on who is more superior or entitled to get the food, or which 10 people represent the ruler's religion or national ideology more.
Is these comparisons aren't really that good, because they compare idea in a situation that already sucks no matter the system. And what measures to apply in those situations depends on the specifics of the situation. Like if you have 100 people but only food for 10 people for 14 days but you know that the deserted island is frequented by a ferry once a week then it might make sense to spread that food equally to all so that most people survive. Or maybe even to spread it according to need so that those who are at the risk of dying get more than those who can stay longer without it. Or if you know that no one will come and that this is all you got, then it might make sense to invest in self-reliance and try to gather new food by other means. Maybe that reveals skill sets most valuable which require special ratios of food.
So the left-right description in terms of actions is pretty ambiguous and not actually set in stone. What is more useful is to define them in terms of motivation. Like you could define left as egalitarian and right as elitists, then the left wing position would argue that the lives of everyone matter equally while the right wing position might be that "I" matter more or that, "my peer group" matters more or in general that people should be thrown under the bus without consideration in favor of the rest. But again they could do that out of principle or out of necessity, so just because the action is the same the motivation can vary drastically, between a someone that is in favor of unequal ratios because of a support of equal rights to live and an unequal necessity of food or someone who is in favor of unequal ratios because they don't like to share food.
That all being said, left-right spectra also have some obvious advantages. Like often enough the divide within a country about an issue can be summed up with two opposing views or can be narrowed down to to. And if you can do so you can have a binary vote, so it's either the one or the other. Now it doesn't mean that this is always a good idea, but at least it gives you majorities rather than just pluralities. Like the more axis and complexity that you introduce the more possible alternatives you have and the less likely you'll find majorities.
Like the center of a 1 dimensional line from 0 to 1 is 0.5. Now if you apply a +-0.25 margin you have covered 50% of the spectrum.
If you look at a 2 dimensional square from (0,0) to (1,1) then the center is still (0.5,0.5) but now the +-0.25 margin (so the center square with side length of 0.5) is just 0.25 so only a quarter of the square.
In 3 dimensions the center cube is only 1/8th of the cube and so on. So the more dimensions you introduce the less likely you'll have a central majority and the more it becomes fractured and complex to administer, while a 1d representation gives the illusion of simplicity.
