What is your case prep routine for once fired brass bought as factory cartridges? Do you trim it if it's already under max length? Do you bevel the case mouth if you skipped trimming?

1. I don't trim if it's under maximum length unless I'm going to crimp which I only do with cartridges with heavy recoil to be shot in guns with magazines or cylinders.
2. I'll bevel case mouths of untrimmed once fired brass if I'm going to seat flat based bullets but not for boat tailed bullets.

Depends a lot on what the brass is. For my revolver brass after I clean I sort by length. Makes crimping easier.
For rifle reloads I tumble for an hour in walnut and then remove the spent primers. I then neck size, trim, taper and bevel. I find this way I don't normally have to trim again for most loads and I know that all pieces are the same length (most aren't) when they come from the factory. I then polish for an hour or so in corn before adding new primers. They are then ready to reload. For handguns pretty much the same except I use a FL resizing die and I don't trim the brass.
Previously fired pistol brass I just throw them into the tumbler to clean and then reload it. 1st time for rifle brass out of my guns the same thing. Brass that's been fired from other peoples rifles gets better inspection, trimmed if needed.
The only brass I've found that needed chamfering is brass that's factory new and those that have been trimmed.

For hand gun, I don't bother to trim.
For rifle I trim after the first firing. That way they're all the same & almost never have to be trimmed after 2nd & 3rd firings.

Pistol brass: tumble it and load it.
Rifle brass: tumble it, deprime in separate operation, lube, size, trim. My Gracey, Giraud, and RCBS trimmers have three way cutters which trim, bevel, de burr.
I trim each and every sizing. In my experience brass lengths the most on first firing, but also lengthens considerably subsequent firings. If I shoot the stuff in the same chamber and size with the same sizing die, around firing 4 or 5 the stuff grows maybe .001, .003”. If I shoot in a different chamber and size in a different die, the stuff starts growing big time. No idea why this happened, but it does.
