ME1 I have mods for unlimited Mako boost and jump jets, squad default armor always, N7 heavy armor always, a lot of quality of life mods mostly like unlimited sprint.
ME2 ill never play again without choose your own weapons, I can't stand being railroaded into using SMG's, we are special operations and should all be trained on the basic pistol and rifle regardless of class. Additionally squad weapon change mod that gives Miranda a sniper, Jacob an assault rifle, Mordin a shotgun and a few others. Just get away from the "SMG's for everyone!" Bullshit that is a huge mole on the otherwise perfect ass of ME2. Unlimited sprint because once again we are spec ops and should be able to run more than ten feet without having a heart attack.
ME3 I can't recall because I don't really play it all that often.
Ok, I have a whole list of mods I used on my last play through.

I also downloaded extra outfits, hair packs, and custom character designs.
It’s going to sound silly, but the first mod, and most aesthetically necessary for me, is one that fixes Kaiden’s stupid, melted Lego hair. I can not stand that melted lump of plastic on his head. I only started pc gaming a year ago, and a mod to fix his stupid hair was the first mod for any game that I ever downloaded.
The other mods I consider essential are the ones that cut out the mini games (I can do the stripped down Simon game on ME1 on console, but cylindrical space frogger was beyond me) and the one that lets you scan all the planets in 2 with one probe. That one is a legit lifesaver, since I have something called Ehlers-Danlos Syndrome. It made all my joints really weak and prone to sprains, and holding the trigger down to scan got painful quickly and I’d often have to stop gaming because I could feel my finger about to go. That mod means far less strain on my fingers.
Another good mod I like is the one that revamps the dreams in 3. Stone of the revamped dreams are a bit meh, but I just got to the last one before Priority Earth, and it really hit me.
