As soon as you get the death confidant (will happen through the story and fairly early) your first priority is to immediate get it to level 7 and buy sp adhesive 3 accessories for all your party members (cost 50k each at rank 7, 100k each at rank 5), you will need Guts to spend time with them so rank Guts up asap

Do dungeons asap and in as few days as humanely possible, you can get through an enitre dungeon in a single day once you have the sp adhesives

Temperance is another high priority confidant to rank up as soon as its available, Fortune is really helpful

Youll never do everything in one playthrough, so prioritize leveling up social stats because you WILL need them at certain levels to hang out with confidants and social stats carry over to NG+ while confidant ranks dont

On a first playthrough, besides the confidants i mentioned above, i feel like focusing on ranking up your party members confidant level should be a priority over others, they give nice skills that are useful in battles and level 10 will power up their personas

This wont make sense yet but dont waste a day in mementos unless you have multiple targets to take down, generally not worth the time otherwise
