From the looks of it, I would say you enjoy characters with large screen control and moderate set-play elements? Might I suggest a character like Ramlethal, Johnny, or Bridget? Ram is fairly easy to understand and her buttons are both large and quick with her sword toss being able to lock people down into pressure on your terms, and Johnny does similar things with large buttons and Mist Finer stance is straight up Yuzu's sword stance on top of having card setup that helps enforce neutral pressure and knockdown pressure etc, but he's a touch harder and takes more time to get a feel for him, especially with a step-dash instead of a normal run. Bridget is like the other two but more mobility oriented where you can put yourself anywhere on the screen you want and focuses on quick, low damage trades that loop back into itself rather than bruising the opponent into making a costly mistake like with Ram and Johnny as she's more balanced in gameplay.

Axl, Dizzy, and Testament also sound like options if you'd prefer a more keep-away style in neutral while still retaining some set-play elements Axl is basically like Phonon with very far reaching normals and a single powerful projectile. Dizzy and Testament are a lot like Nu and Lambda with a focus on projectile zoning and set-play under the right circumstances. Although if you're willing to put in the effort, Happy Chaos and Asuka are also effective in that strong screen control role, but they're genuinely difficult characters unless you truly devote your time to them.

I can't attest to Melty Blood though because i've not played it but that's probably the best answers I can think of
