I am just trying to fully understand the compromises for each length. The give and take.
My PCC lever guns all wear 16” barrels, in .357. .44 and .45C. (9mm too, but that’s a semi-auto.)
The 1892 action and the 16” barrel go well together, making a handy yet potent little rifle that fits into vehicles nicely.
.30-30, 35 Rem, etc. are great in the 20” barrel-length carbines made popular by millions of hunters. They are also very good for PC rifles, but I prefer the 16” myself.
Anything longer than 20” on a PC rifle rapidly becomes unwieldy, and pretty much defeats the purpose of a handy rifle shooting a limited powder capacity cartridge. (Like pistol calibers.)
These are merely my opinions. They’re no better or worse than anyone else's, and they’re worth exactly what you paid for them.
My centerfire levers run from 16” (.357,.44,.45), to 18.5” (45/70), to 20” (.30-30’s, .35 Rem) to 26” (45/70). I had a 20” .357 and a 24” .45 Colt in the past, but those guns were sold off years ago to fund other projects.
I think you did well. The Rossi 92 is a fun rifle to shoot..Check out Stevesgunz.com for Rossi 1892 stuff like metal magazine followers, trigger/hammer spring kits, safety delete caps, etc.
Stay safe.
