Scanned my own wedding photos at 1200 DPI a while back and honestly it was a huge waste of time. All that dust and scratch stuff you are seeing is just how old paper and film actually looks, it is not some hidden problem you need to fix. Bumping the res just makes you zoom in on stuff nobody would ever notice when the photo is sitting in a frame or a normal sized print. You spent two hours poking at tiny specks in Snapseed and now the dress probably looks fake and smudged when you look at it up close. Half those "flaws" are part of the photo's history, and wiping them out with a computer app sort of erases that. Turn the res back down to 300 and the shot will look exactly like it did to your grandma, dust and all.

The part people sleep on is taping both ends before you even pull the wire. Do that and you never play the guess game when you're terminating. I keep three colors of tape in my pouch, red for hot, white for neutral, blue for switch legs, so a glance tells me everything without reading a single flag. On a 48 port panel I can label, dress, and land the whole thing before lunch. Shrink still wins in wet or high heat spots where tape glue turns to goo. For dry indoor racks though, tape all day.
