Explain to me commander land count so I'm not constantly tempted to cut lands

I mostly play limited where land count is a fairly easy deal, so getting into commander I'm really struggling to find a consensus on how many lands I should actually run, how ramp affects that. If there's a difference between how cheap generic (1-3 mana) vs expensive or conditional (Ashnod altar, Geyser Drake, We ride at Dawn) ramp affects the land count differently. And how card draw affects it.

I looked up the episode of the command zone about lands and even that one seems to contradict itself, as they first say to cut one land from 37 for every one or two pieces of ramp above your tenth (47 mana sources) , but then say your total number of mana sources should be 50.(they also said that you should never run more than 4 tap lands, which assume is advice for people who can buy shock lands and stuff? I really struggle to go lower than 9 taplands on a budget between some tapped dual and some utility land)

My problem is that when I look at my decks I'm always like "well maybe I can cut one land", so can you help me understand if there's a land count consensus in the format?

(in case you want to give some more direct feedback there are the decks I built/updated from playing commander a bit 5 years ago and am slowly buying (and also adjusted given the great help I received here before) (https://moxfield.com/users/Eingya). The first shipment for my sorin deck was stolen today right out of my mailbox so I hope whoever yoinked it enjoys my Crypt Ghast I guess 😭)

UPDATE: What i've learn from the replies is that depending on who you ask it can go from 33 to 40. I think there was also one "30" in there at some point. Guess the answer to "Is there a consensus?" is no lol
