not sure what you mean; because all the builds you’ve linked are 100% pure endgame builds
all these builds can comfortably beginner farm “endgame”
the only way for there to be something “between” beginner farm and real endgame farm, would be a beginner-endgame build that was partially transitioning (item-wise); otherwise it’s an actual endgame build; since those require a “full” specific setup of XY legendaries that are random drops
most builds in the beginner build compendium can, comfortably, farm SR 50+ if not even 60 or higher, on Ultimate (at least the ones i’ve tried),
endgame builds aren’t as much about "farming capablitly) since they can basically all do SR 65-66 on Ultimate or 75-76, but about optimized performance, “making the same feat but better/faster”, ex Crucible 170 in 5 minutes instead of 7minutes
and since SR 65-66 is about the most optimal farm spot, without a fully reliable build/“endgame” build, you don’t really need a full endgame build for farming (65-66 farm), unless you wanna step it up the final notch for 75-76/150-170 farm within “fast meta times”
