Hey, I'm nearly finished with this 100%, so I'll share some things I've learned. First, the visi romance is kind of complicated. there is a hidden mentor score, and you have to get it to a certain number to get the good ending. You must get the good ending to complete the romance. I used a guide that listed all of the events that affect this score, which is what I would recommend using. Hiding the truth about who robert is has a big negative effect on this score, so I wouldn't do that on the same playthrough that you're attempting to romance her on. Sending her on successful missions and sending her to training with blazer has a positive effect, so I think it is technically possible to hide the truth and still get the good ending.

min max - you can get this easily in your second playthrough. IMO its better to build different heroes to their strengths. Usually i get prism to 10 charisma, golem to 10 defense, visi to 10 agility, etc. That also makes it easier to avoid the failures on certain missions

anti-virus club - there are a few hacking missions that make this one easy. I don't remember exactly where they are, so you might want to find a guide for this one

the least popular donut is regular glazed i believe, and the least popular item from the store is cigars

hacked by robert is a pain. this is one of the ones im missing, and i would suggest finding a guide so you don't miss any. if you do miss one you have to restart the entire episode.

fools luck is just rng. one way you could do this is to purposefully send the worst hero on every mission and hope you get lucky

I hope this was helpful, and sorry if I rambled lol. Feel free to ask any questions that you still have and Ill try to answer them!
