If your goal is character creation with no specific campaign to join or game to play, GURPS and Hero System are still outright winners. D&D 3rd edition not bad either, if you make something above 1st level.
The question is vague, and there are multiple ways to approach it. The perfect movie for me is one I want to watch. Movies that I think are perfect approach perfection is a different category. We can (and should) discuss both. Perhaps better to clarify which you mean ('perfect for me' vs...
This is apparently specifically for D&D 5e (2024), and specific to fighters.
To each their own. I can't go online without being advertised 3-6 new 3PP products that are for the most part new subclasses, feats, spells, and monsters.
Sure.
Something like the AD&D 2nd edition Complete Fighter's Handbook, or more importantly what it aspired to do. Like, if you wanted to play a bronze- or stone-age campaign, not just how to do it, but how to do it but still fight dragons and ghosts and such. Same with a sea-faring campaign...

In my home 5e(2014) campaign -- the one my co-DM learned from -- I had a house rule that you didn't regain any hp on a long rest, only all your HD. He repeating it (as a gamebook rule, apparently forgetting or having missed that it was a house rule) to a group of kids he was teaching to play the...
If that's how you feel about the matter, more power to you. To me, 'I didn't do the thing you wanted me to have done because I'm ignorant of it,' is hugely different from, 'I didn't do the thing you wanted me to have done because it was never my goal.'
