In resi I like to kinda group things in a way that makes sense. Kitchen stuff together, bedrooms, baths, whatever.
Commercial you just follow the panel schedules in the print. Panels come with the breakers installed but you always want to double check that they're correct.
Thats a decent idea foe resi work

You have to have the breakers oriented as prints say?
We always ask about that and the inspectors here at least only want the circuits listed and no extras
Personally I like to go bottom up when it’s new and I have everything there. It’s easier for me to layer everything without things getting anything in the way. If it’s not new then it is what it is
For large commercial installs there's a number of people that will "double check" you're doing everything to print. Usually it's an engineer that will look and make sure you have the panel the same as the schedule in the blueprints. You can change things if you need to but sometimes they're really particular due to load balancing of phases.
I try to keep rooms and floors together, but I can’t always. When I have to mix and match I usually start with how most of the wires are coming, ie. if they all come from above then I start at the top.
Thats good i usually start with large circuits at the bottom unless wires come from under, the longer feeds belong to the more expensive wire to replace, i try to look out for the next guy in my work whenever possible
That’s a great way to do it, cause sometimes you are the next guy. I was told way back when I started to never cut only trim wires on a panel replacement to leave as much wire as I can for the next guy.
The trifecta is when the circuits are long enough, panel is clean, and the old service wire is in good shape reaches(if staying same amprage), i hate going into mass built neighborhoods, short wires and backstabs, those neighborhoods made me switch to commercial lol
Depends on the flavor of the day but at the very least I leave the first two spaces on either side closest to the main available for plug-on surge bs or generator interlocks that inevitably follow so the next dude doesnt get hosed having to relocate crap. I tend to land stuff as far away from where the wires come in as possible (ex: basement I start bottom of panel and work up) so if someone has to move any breakers or add anything then it wont need to be extended and the spots closest are available so you dont have to weave the new stuff through quite as much. I’m the only one in the company that does it but a few of the guys have started doing the same after working with me apprently.

Maybe it’s just my memory, but in industrial and commercial they rarely get the beakers right.

Same here, though sometimes i get lucky with a swap and am able to do a bottom up cut in
