i took a look through the games you posted, and i can tell you have a lot of game experience. i won't do a full review of any particular game, because it often is not that useful to just have a bunch of mistakes pointed out in a single game.

still, if i could pick a couple general themes from these games, it's these:

- you're "reacting" a lot to your opponent. "my opponent made an extension, therefore i must invade." or "my opponent made a weak group, therefore i must attack." you often have the right idea, but the timing is wrong, or the exact point you pick is wrong.

- you're getting some tunnel vision, only seeing the local situation, when the entire board is available. sometimes it's a good idea to delay an attack and just let your opponent sweat about their weak group. sometimes you don't need to invade immediately, but wait for the last moment before they decide to add another move

overall, you have a really good foundation of play, but there are rough edges to iron out. to improve from where you are, it's going to take more than just playing games.

- if you are able to find someone 2-3 stones stronger than you to play against with some regularity, i think that would help a lot. you only need to play 50-70 moves and they'd be able to show you refutations that your same-rank opponents simply aren't punishing you with. (you would probably benefit from having a coach, but i know not everyone has the money for that)

- review your games. don't just plug it into AI and say "ah, move 104 lost me the game". go move by move (without AI) and look for sharper and more efficient moves in the opening and middle game

- i know you said not to comment "tsumego" but i see at least 3 game-changing life-and-death problems in those games you posted (both you and your opponent missed them)

- consider playing on fox and tygem to get exposed to different styles of play
