My "default" configuration, on those cameras that have the option, has become 1/1500 @ f/8 TAv.
Where I can, I leave the camera Mode Dial set to "my" User Mode so I know, when I switch it on, where it's going to be.
From here I can wriggle my e-dials for a more "suitable" setting as appropriate, if I've got the time, but at least I'll not miss a shot if I'm in a rush to catch a subject in a hurry

Other configurations are available … macro, infra-red, monochrome, street, pseudo-Katen etc. … these are all set up to suit me as a primarily JPG shooter, often with specific lenses in mind.
They'd possibly need to be tweaked to suit personal preferences, so I'll not clutter the post with my choices, but leave them as ideas for anyone who's interested

A point to consider when using User Modes :- If, having diverted from your original settings for whatever reason, there's no need to re-adjust all the settings to revert to your preferred starting point … just switch off and back on again

Enjoy!
