I’m looking for anything to read that’s happy and hopeful and about an MC using his/her future knowledge to change other’s tragic fate. It can be any online novel (NU, RR, FF, etc). I’m really in the mood for something that’s not depressing and about a person saving people, overcoming fate, and making happy endings. It can be SI fanfic or meta knowledge or a second chance thing or time travel or future sight, etc.
I was going to throw out A Will Eternal and Everyone Else is a Returnee, but going by your reading list you've read just about everything I'd recommend and more. So the same is probably true for Mother of Learning. Hmm..I didn't see I am the Monarch or Amber Sword on your reading list, so you might want to try those. They fit your criteria.

For happy + light story + suitable with tea company = Read JP LN [REC] Mushoku Tensei (the life of Rudeus Greyrat) - Completed Konosuba Baka to Test Oregairu (a bit bitter, Hikigaya problem solving) Long Live Summon (I like the first arc, about how to cultivating beast and adventure in Tong Tian Tower as well as everything for fourth mother) Danmachi N.B. If you don't kind harem, there're plenty of happy go lucky harem story in JP LN, e.g. Isekai Meikyuu de Harem Desumachi In Another World With My Smartphone Seven ..... (I forgot, too many silly title)
Long live wasn't bad until you realize that the McCain only cares for female characters I realize my phone typed it as mccain which will stay because I think its funny. I meant MC for those who care
Relic of the Future by Coeur Al'Aran. Jaune in his 20 yo body time traveled to when his classmates are still 5. Then he proceeds to do anything he can to change the future where everyone dies. Right now he already changed quiet a few people's lives.
Mushoku Tensei - the part where he change other people's fate was supposed to be a spoiler though. Moon led journey - he change his own fate without being aware of it. Tate no yuusha? Spear hero - i haven't read this sequel but spear hero supposedly changed the fate of other with his second iteration including Naofumi turning into generic harem protagonist.
You could check on this thread, there are several excellent novels from outside nu/rr for example lightning in a bottle (completed) most of the other novels are +18 explicit however you can avoid most or all of it with no problem.

This is a Star Wars Fanfic ~400k https://archiveofourown.org/works/8543680 It's about a Leia from the sequels finding herself back in ANH on the deathstar just before vader interrogation. It's amazingly well written for a fanfic. there is character development, and the interaction between characters is realistic and in character. I especially like the fact that the changes she makes have repercussions outside her prediction or control, that and that her memory sometimes fails her. to many of the fics with this theme have their MC using their future knowledge to become godlike or to control everything, to the point of becoming ridiculous. No doubt my favourite fic that uses this plot bunny. Regularly updated (and even if it was dropped what has already be written makes it worth the read) On a side note I second Volcanic Age, a webtoon, but pretty solid so far. (especially good art) iIt's however on a pretty long scheduled Hiatus, between seasons, so be warned. It's Korean BTW
Can you tell me about this novel you got in your signature ? I am interested if it got fluffy romance and no really dark moments.
I am on an undefined hiatus on that one,(college keeps me to busy, I barely have time to read) It was supposed to be a slice of life but driven by a solid and deep plot, with some fighting here and there. So no dark themes. All I have written so far however is a Slice of life with some hints of what was supposed to be a turning point of my planned plot. In my plans romance was not a focus but it was a part of the story. you will not find any of that in what is written. (I could have left some hints about a love interest or not I don't remember.) If you give it a shot, please leave a comment and/or review, if I'm ever going back to it will be thanks to comments and the reviews
Kinda wanted to add, if you continue and you successfully write fluffy loveydovey romance, i would rush to read your work.
